Opteron 170 gaming trouble?

[PZEROFGH]

as you know i installed my new opteron 170, i did a bios flash and i even installed windows XP professional, from XP home. and when i play cs i "lag" and i just studder all the way across the screen, and i even got banned for "speed hacking" though i was just "lagging". i havent tried any other games, because i cant log into my bf2 accoutn cause the server "rejected" me.

when i press CTRL+ALT+DEL i see two graphics, so i know windows is recongizing two cores

oh yeah my ping is below 100 most of the time and i didnt lag before

Try reinstalling it (game). Maybe the upgrade screwed it up.
