I've had a 3870 in my comp for a while, and it worked pretty great considering my system only had about 1.5 gigs of ram.
Well recently I upgraded my system to 3 gigs of ram and did a clean install of Vista only to find abysmal performance. Using MSI Afterburner's overlay I found that the culprit was the fact that my GPU never goes above a 10% load. If anyone can help with this issue I'd appreciate it.
