CPU
• Supports Socket A (Socket 462) for AMD® Athlon™ XP/Athlon™/Duron™ processor
• Supports up to Athlon™ XP 2800+ processor
Yep, there ya go, it has room fro improvement.
The agp port is 8x, so that's as good of an agp port you can get.
Now, there's no metion wether you got the version with the built in ethernet port, so ask your bud wether or not you'll need a NIC. They're aboot $10 cad, so no biggie if there ain't one.
I agree with the others who say the AMD AthlonXP 2000+ will be better than the celeron 2.8GHz for gaming. The cache size makes it only good for a student work computer. Heck, I think my old AMD K6 700MHz (I think it was that much at least..) cpu beat down a 1.2GHz celeron cpu, lol.
I dunno, if I were you, I'd dig around local computer shops and see if you can find an old vidcard cheap. If you're lucky you can find a geforce 4 ti for under $90 cad, even an old geforce3 would rock. That will beat out the fx5200 (oh c'mon, like the fx5200 would even crank out the visuals, lol). Don't get a geforce 2 or geforce4 mx440, the fx5200 is well, barely better than those.
In the end, it's a simple matter of if you wanna game with your buds. I'd say if they're willing to help you out? they're good buds man, stick with em'.
