With all there is on the web I don't have to repeat that here. But it is worth noting that i7 laptops, while nice and fast all suffer the hot surface issues. If you must have a cool surface laptop, the i7 and the AMD mentioned is not for you.
I didn't see any note in your post that hot surfaces would be an issue for you.
AMD Phenom II Quad-Core P940 vs intel Core i7 740QM or 720QM
which is better for someone using programs like Photoshop, Autodesk 3dmax, rhino 4.0, and AutoCAD. is the i7 worth $70.00-$120.00 more or would my money be better spent on memory upgrades. for example 4 Gigs to 6 Gigs for about $129.00
Also what your opinion on Toshiba?
hear is a link to the computers I'm considering.
