Computer / Laptop Suggestions

Hello,
I am naive with computer hardware graphics, and, currently having Daz3D being slow/jittery in navigation + my macbook pro (2012) produces a fan noise as it slowly renders.
Any suggestions on which specific laptop/computer to buy off the internet?
Thanks in advance!

Does it have to be a laptop? Lappies will always be pretty loud if you want them to be any good as a render box.
In general you're probably better shopping for specs rather than a specific model. If you can give us an idea of your budget then people can make specific recommendations.
