Computer build/setup questions?

That set up is good as a mainstream gamer and cam handle high settings on your 19" monitor. The triple core processor may be a bit of a bottleneck at high settings for multi-threaded games like GTA-4, BF Bad Company 2, Metro 2033, etc. and upcoming games. But it is really upgradeability that extends the life a PC. Just upgrade processor when the bottleneck becomes unacceptable.
