I'm experiencing some pretty terrible lag for seemingly no reason at all. I'm running an i5-3570k, a 256GB SSD, 8GB of RAM, and 2 GTX 670s 2GB in SLI (one is a GTX 670 2GB SC, not sure if that matters, but it is in the top most slot). I've done a factory reset on the entire computer to try to trouble shoot any issues, but to no avail. The lag is noticeable in games and in general web browsing where the screen will freeze for 3-5 seconds while the sound remains unaffected. During the moments of lags, the CPU plummets from around 60% usage to 0% while monitoring activity with software. If I need to provide any more information, I'll be happy to do so. Any help would be so awesome since this issue is preventing me from providing an enjoyable live-stream.
