Best thing to do...realize that the gaming mags are just a starting point and as far as rendering goes, video memory is a very high priority. So, everything up until they start going off on how more than 2 or 3 GB on a video card is excessive and just panders to whatever the catchall of the day is, should be considered good advice/reviews...
An 800 watt PSU should be more than adequate to power your system with a single GTX 780 Ti. The 1000 Watt+ units are only really needed for users running multiple graphics cards in SLI. Having said that, not all power supplies are created equal. Cheaper PSU's often exaggerate their performance specs and often do not provide good, clean power under all loads. Or they fail. There are a few good manufacturers (be careful not to confuse brands with manufacturers) out there that produce consistently good PSU's - you just need to do a little homework. JohnnyGuru is a good source of info on various power supplies, if they have actually reviewed them.
Having said that, there is nothing wrong with getting a 1000 Watt PSU. It will have lots of overhead and will only use as much power as the system requires. It simply will never be required to come close to its capacity in most systems, so you may be paying more in terms of purchase price than you need. Lastly, I would sooner purchase a good 650 Watt PSU from the likes of Seasonic, than a 1000 Watt unit from a second tier manufacturer even if the price were the same.
My new card needs a PSU with "About 70A on the +12V Rail" more or less, my actual PSU is 800W but is low on +12V Amps.
Do you have a Web Media/Portfolio?, I wonder what means 40 years of Professionalism in Graphics, considering I'm 42 years old...
I'm not certain where that is coming from. The GTX 780 Ti maxes out at 250 Watts, which translates to 250/12 = 20.83 amps. The rest of your system combined might draw a similar amount under full load, so the need for 70 amps on a single +12v rail puzzles me (12 x 70 = 840 Watts). Where is the quote from?

Memory is important when it comes to what will render on the card. If your scene does not fit on the card then the card is not used. If the scene fits on the card then Number of cores and speed of cores are what count.
Note right now, it appears the best bang for the buck is one or more Titan X cards.

No portfolio....
I got stupid lucky and worked for a large company in their engineering department doing mostly technical stuff. I also had an electronics technologists degree (thanks to the Air Force) which helped me get the job. The job wasn't terribly glamorous but the pay was steady and I'm now retired on an indexed pension (Yippee!). I'm still working part time providing all manner of graphics to a small company that makes online technical training. Again, terribly un-glamorous but the extra money is nice and going into an office three days a week gives me the social interaction I crave.

I'm thinking on future, get more cards, updating the MoBo and CPU, and sincerely being stopped for a miserable PSU really is pissing me to the max.
DevianArt page?, neither a personal website?, nothing? or a Daz Gallery?,
dude come on!, even me, a mediocre 3d artist have a simple devianArt page!!
I'm sure that is not exactly what you intended to say, Spooky. The Titan X's may be the biggest bang currently, but not for the bucks at about $1300 a pop hereabouts. That's more than a lot of folks spend on their entire PC.
This may be common knowledge already, but I would just like to concur with the recommendation for the 780 TI. Based on my research of various render engines (Octane, FurryBall, etc.), their tests all reveal that the 780 TI is one of the best cards for rendering money can buy, even better than the newer 980 (for whatever reason, Nvidia has crippled their new 9xx series in order to make the Titans more desirable). Here are their benchamrks;
Octane Benchmarks:
https://render.otoy.com/octanebench/results.php
As you can see in the Octane benchmarks, eight 780 TI's in SLI is the fastest combination possible, beating even 8x Titans on their benchmark (a score of 895 vs. 844). A single 780 TI scores a 102, and a single Titan Black also scores a 102--the highest score for a single GPU system--faster than even the newer 980 which scores a 99.
FurryBall Benchmarks
http://furryball.aaa-studio.eu/aboutFurryBall/benchmarks.html
Again, the benchmarks for this render engine show the 780 TI is at the top of the list in all their stats.
Perhaps this is further proof of the importance of CUDA cores over VRAM. With only 3GB of VRAM, the 780 TI outperforms almost every card with more VRAM (except for the higher end Titans).
Hope this helps a bit.

An afterthought.
For a while, I was thinking of getting a 770, and saving $100. One would think a 770 would be only marginally slower than a 780 TI. But the benchmarks above reveal a significant difference between the two cards.
The 770, which is supposedly only one step down from a 780, scores only a 57 vs. the 780 TI which scores a 102, nearly twice the score. Note also, two 770's in SLI score only a 113, which is only slightly faster than a single 780 TI. So a head-to-head comparison of a 770 4G vs. a 780 TI 3G is no comparison at all. The 780 TI seems to be the king of the hill for rendering, and can be had for a mere $300 on ebay.
What are your thoughts?
Davide
Thanks for the research, thricegift, I'm a proud owner of a 780Ti now.

That's more than a lot of folks spend on their entire PC.Power vs. Price. Titan X can be had for between $1000 and $1200. http://www.amazon.com/EVGA-GeForce-384bit-Graphics-12G-P4-2990-KR/dp/B00UVN21RQ for example.
Which is less than the price of 2 x GTX 980 but, depending on how you measure it, can be considered more than twice the power of a GTX 980.
Nope, not a thing. I have no need to show off. My portfolio is for prospective clients/employers only and being (mostly) retired I have left it to languish untouched. My personal stuff is mostly sick, twisted, perverted, and just plain messed up and stays on my hard drive. I love to shoot HDR panoramas for IBL which I share with a few internet friends but that's it. I make some of my own content but the rampant piracy means it doesn't go out in the wild.
...and you really shouldn't be calling someone my age 'dude'. :-)

All right, Sir.

And to fortunate Mac users who have an older Mac Pro (model 3.1) this is best option as it needs only two 6-pin power cables the card can run safely on the Mac Pro’s internal power supply.
Edit
Oh, you need a custom flashed card available at macvidcards
$1,177.99 is too much for me. :( Also, only a video card that is less than 10 inches long will fit in my computer. Guess I'll just buy a $350 video card with 1,664 CUDA cores and 4GB 256-Bit GDDR5 VRAM instead. Thanks for posting the information though.
edited for clarity.
Would this be a good card? CUDA Cores: 1536

Still waiting for DAZ and NVIDIA to offer a deal to us but as it is I need to get this done.... not waiting any longer.... Should have presented these "deals" when DS 4.8 went live, you know... synced the whole release... guess not....
Found this one today at NewEgg...
http://www.newegg.com/Product/Product.aspx?Item=N82E16814487069, got a few more CUDA's... price is OK too!
I'm starting to look for a video card to render with as well. Looks like I may be able to keep my ATI card and have a nVidia card for rendering in the same box. It would let me keep using my machine while it renders.
Just read that the 980 Ti will come out Tuesday, June 2nd, 2015. It has 2816 cores and 6GB of RAM. Wonder how it'll compare to the Titans and 780 Ti.
I'm seriously looking at the Titan X (3072 cores). 12GB would render any scene I could come up with. But man, that price tag!
I think AMD really missed the ball on GPGPU. They're coming out with the R9 380x 8GB (2816 cores) which is supposed to be faster than the Titan X. They're also releasing a new card called "Fury" (4096 cores) that has HBM memory. It's supposed to have 4.5x the bandwidth of GDDR5 and 16x that of DDR3. But none of them can be used to render with any unbiased renderer. Octane looks like it's still a ways away from having proper support for OpenCL or a plugin being available for DAZ3D. AMD has historically been faster in OpenCL. But they've hardly ever updated their OpenCL drivers and just don't seem to be interested in gpgpu. Maybe it's not that big a market. But the number of cores on their video cards are just sitting there in my machine unused (except for video games).
edit: Correcting date of release of 980 Ti. It comes out Tuesday June 2nd, 2015.
in a less than 8 hours I will buy my new PSU for the GTX 780Ti, cross fingers, when installed I will post the render speeds.
2880 Cuda cores...almost porn.
Ok, after installation with a new PSU and a lot of scary setup (a jumper not in place got me creeps for a while), there you go, very good numbers for my workflow, iray sun is very demanding, hdri is faster.
Just a headsup. Newegg has this GTX 780 6GB refurbished running until tomorrow. There's an additional 50 bucks off the listed price as well. So for about 309 you can get a card with 6GB of VRAM which runs pretty neck and neck with a GTX 980. :)

I got mine delivered today and it actually cranks out a few more iterations per render than my 980.
NEBER MIND........
Got it. YAY!! Thanks for the info on the card Zebratech! Great deal!
@zilvergrafix: You got that scene to do 2000 iterations in 8 minutes!? Oh man. That's awesome. I just bought a Titan X. Expensive, but I know I'll make use of it. Can't wait for it to get here. I like scenes with many lights and subtle shadows, etc. Looking forward to seeing the results. Your post makes me very optimistic.
You're very welcome RAMWolff! Hope to see some neat Iray renders from you. ^^
Probably not right away... busy making content but really needed the upgrade. What I love about this card from what I could see is that it's also equipped with two DVI ports. YAY!!
Titan X, whoa!, well I had that like an option, but it was 100 USD more expensive than the GTX780Ti.
the negative side of this is...the credit card debt...*sigh :shut:
Below, a new record??, single figure, just HDRI lights, Quality turn off, firefly ON.
