Thanks for all the help so far!
I think I'm going to return the 6800 and save up some coin for a better card. What's a decent AGP card I can grab for around $225 that will last me a little while.
Specs:
Athlon FX-51
1.5 GB PC3200 DDR
AGP 8X
I've been searching around (Ebay etc.) and could only find 6800 GS/GT for aout $100 USED. This card is brand enw so I figured $140 was a decent price, certainly the cheapest I could find at any online retailer.
I've been experiencing computer crashes quite frequently for a few weeks now. The obvious culprit was my Radeon 9800 XT which appeared to be overheating (even with an upgraded cooling system). I purchased a Geforce 6800 GS for $140 as a replacement, and it turns out the real problem was my sound...
