Thanks loonym. I have my 9800stx clocked to 800 core 1200 memory and 2025 shader can run ati tool for a half hour no errors. I am using driver 175.16 and there is a new offical and beta driver out that I have tested breifly (175.19 177.39) I have heard bad thing about them but I plan to do some more testing on my own now. I plan on geting another 9800 for sli soon crysis should run great other than the popup it runs really smoothly on high @ 1680 x1050. Do I really need anti virus protection? I think that and my firewall cause me alot of these problems I dont really surf the web on this pc.
