specs are: CPU: Athlon 64 x2 3.2GHZ Black Edition 6400+ RAM: 4GB 800MHZ DDR2 GFX: XFX 5870 GPU at 900mhz MEM at 1300mhz HDD 80GIG Maxtor 7200rpm (temp replacement of my failed 10,000rpm raptor ) MOBO: ASUS M2N-E SLI PSU: 800WATT Thermaltake crossfire/sli ready (not sure exactly but over 30amp on 12 volt rails) Got latest drivers for everything cat 10.5 ect. Temps are all around 50-55 under load for cpu, gpu ect. Games are all patched. Services have been tweaked for minimal background mem and cpu usage. Virus scans and spyware scans are done regular. Every game gets reduced to a 20 frame per second crawl multiple times during gaming including oldies like counter strike source when things get hectic. I cant see the 5870 having trouble so im thinking my cpu is holding it back?
