Hey guys, i just upgraded my gaming/mining rig..
basically replaced the core 2 duo with an intel i5 2500k..and added another 6950
now the problem is that when im mining with both the cards(both cards reference, unlocked and clocked at 950mhz), my cpu usage shoots up to 50%..(using latest version of guiminer)
first i thought it was a problem with the 11.5 catalyst + opencl drives and so i went ahead and installed the 11.4 drivers..makes no difference..
i remember guiminer using only 1 to 5% of my old core 2 duo...
