Hi, Im after a desktop replacement, for general use. 3d / rendering work, and some gaming. I'm looking at 17" laptops with the new i7 720qm but carnt decide which is best. It basically going to be a desktop that i can take with me in the car so it doesent need to be light or small. I've looked at the hp dv7, but im not 100% on it. Ideally looking at spending around 1000. Any ideas, or experiences?
