Hey guys, I know I touched on this in one of my earlier threads, but I was wondering if anybody had any suggestions for a decent graphics card to put in my machine?

I have the same computer, and I was looking at these two. Do you think they'd work?

Power Supply:

My main question is if that power supply is compatible or not. The dimensions of the basic are listed as 5.9 x 5.5 x 3.4 inches and the one i found is 5.9" x 3.4" x 6.3" . Will it still fit you think?
