This is my first time building a desktop. I'd like to stick around 800$, I realize many people post similar builds, please bare with me. I've done as much research and forum searching as I can on my own, particularly with Tom's articles on performance for best price. But now I just need a final CONFIRMATION from expert users that have been doing this for much longer than I have.
I'm going to playing many FPS titles, Diablo 3, SC2, Assassin's Creed series, etc. I want to be able to play games at least for another 2 years before an upgrade is required. In the future I want to overclock the CPU and crossfire my video cards. I'll be running at 1920x1200 ideally. If I can shave dollars, that's always welcome as well.
I am not 100% on my current video card, the competing GTX580 is just too much more expensive. I've read that driver support for AMD cards are not as good, particularly after the next series is introduced. I'd personally like to go with an NVIDIA card, but I can't really justify their price for performance.
