Hey guys/gals. I am having an issue with my Diamond HD3870X2. It seems to be only when I play Dark Ages of Camelot, an MMORPG game. The game runs perfect for about 1 - 1-1/2 hours then really start to stutter every 10 secs. It's like I am hititng a lag spike and stutters 4 times quickly then runs smooth then repeat over and over. I have tried cat 8.2 - 8.4 drivers + hotfix and still same issue. I even flashed the sapphire bios that fixes the game play / fan fix issues and  still same problem. Like I said its only in this game.

Anyone else play this on the same card or an ATI card experiencing this?
