He built it himself, but he kinda rushed it - I'm thinking he has some compatability issues. He is experiancing some slow downs and some freezes. When he plays CS Source it sometimes freezes. He has duel 7800GT's (with a bundled motherboard, forget which) he also has a X2 3800+ processor. I told him to run a benchmark test as it may be revealing, he did this test http://www.gamershell.com/download_12243.shtml
and scored a 3767.
Hm... anything else I can tell you, or any advice?
