What I have you couldn't brag about at all. But it works fine. I upgrade only when a game I want won't run or I desperately need for graphic/photos, which in the past meant "every 3-4 years or so" but now means "every 1.5 years or so." I need to build a new one soon for the new vid card tech. But I'm not in a big hurry since whatever I build will be outdated 2 seconds after I walk out of the parts store, no matter when I build it, so I probably won't upgrade the MB/vid tech until...a game I want won't run.
