What year are those builds from? That AMD + 550TI combo would be incredibly sluggish in games like BF3 and Arma 2. Oh and you should look at the $900 build - the fact that they recommended an Ultra (garbage) PSU and a sound card that is not needed - that's pretty much a fail right there.

For $600 - this is a far better budget build:

Thanks for the reply. The site claims the builds are kept up to date. Cant be sure though so i brought my questions here. So what kind of settings could i run in various games and at what fps with this build?

Depends on the resolution but the Radeon 6850 is a much more capable card than the 550TI is. If you're willing to go higher (~$750 range), I'd adjust with a better GPU, and a quad core CPU.

I usually play at 1280X720, no AA. Any idea what fps that will get?

If I had to ballpark - probably 30 - 35FPS.

This build will allow you to go higher:

do you happen to have a nearby frys or microcenter, microcenter normally has cheaper cpus+mobo combo but frys just had a hot deal right now with 118$+tax for an i5-2400 store pickup only, which is probably the absolute best deal right now
