I just bought myself an GTX 690 and run both GPU's in D3, but when I use waypoints it's stuttering/staggering loading next place.. And Sometimes I get spikes that lasts for seconds. When I run 1 GPU all is fine, but I would like to be able to use both GPU's since I spent so much cash (I play other demanding games with no problems)

I7 975 (1366) not overclocked
Rampage II
6GB 2000Hz Corsair Dominator
OCZ Agility 128GBx2 RAID 0
Corsair 1000W

I apreciate some feedback on this, maybe some hint on what to do
