So i just bought the rig on the right. And now im having problems in CS:Source. or any source engine game. I start the game, and then about every minute or so it locks up for about 10 to 20 seconds, i mean like the graphics lock and the sound repeats. after 20 seconds it goes back to an average of 100 fps!!!! other then when it freezes it works great. I had the card overclocked, but it does it when its normal speed as well. I thought it was the sound card, tried onboard sound and same result. im using the XG 71.84 drivers. I will try supplied drivers to see if that helps.
