I am looking for a new desktop for myself. I play a lot of different games and do use other programs like Dreamweaver, Visual Basic, VMWare, and occasionally Photoshop. I definitely want an i7 processors. I found two desktops (below) that both have i7. One 3rd gen and the other 4th gen. Is there a significant difference between the two or do you really only notice a difference in laptops? I also want to put a GTX 670 in one of them since the graphics are pretty bad on them.
