I was going to go with a 295 but the price jump from 260 to 295 is pretty crazy, is the performance increase really worth it? I'm also not 100% sure if my PCI-e slot is 2.0 or 1.0, I think it's 2.0 but is there any way to find out a definite answer?
I also wasn't sure if a 650w PSU would be sufficient to run a GTX 295, I know almost nothing about that kind of stuff.
I'm not positive, but I think you can use DDR 2 or DDr3 in am3 motherboards, but am2+ only supports DDR2. Someone correct me if I'm wrong. My system is kind of similar to yours and I run everything maxed out 1680x1050 with like 4x anti aliasing in badcompany 2. Your system seems fine. Can always get a phenom IIx4 later on if you want.
You can max modern warfare 2 no probelm. Crysis you won't max, but I don't know of anyone who can max it with great frames. I run it max settings with no AA and I get 40fps.
