I recently purchased two EVGA GTX 670s and am expecting them to arrive today. I did some research prior to the purchase. Initially, it looked like I had made a good choice. But I'm now coming across a few forum threads that indicate problems with the new 301.42 drivers. The problems are particular to the 670. The reported symptoms include stuttering and crashing. Can anyone out there confirm this? If so, what drivers should I use? I checked the release notes on the newest beta driver and it looks like it contains a few fixes. Will using beta drivers void the warranties? I suspect most of the problems I've read about are related to improper driver installation, but I just want to make sure. The Nvidia forums are down and I can find no official word about the purported issue on the Nvidia website. I also got myself a new monitor and will try gaming at 1920x1080 if my eyes can take it. Will be using the cards in SLI. Thanks in advance for your advice and inputs.
