First off, these are two BFG GTX 285 OC's running on the OC2 BIOS. Just bought them Saturday. I hooked them up, SLI connector and all, booted, let it figure out what was going on (on the latest drivers), and rebooted, then enabled SLI. Everything was peachy king, and I hit up some Borderlands (for a few hours). A total of 4 times in about 3 hours of gaming, this happened: The game froze. Just like hitting pause on a movie. I had to CTRL-ALT-DEL and start task manager, and "Switch To" the game, and it resumed as usual, a few times killing me in the process (slightly irritating). One things that I have noticed is that one of the cards runs warmer than the other by a good 5-10C. Could this be the display driver crashing? A bad card? Should I test them separately? Run a benchmark to see if my scores are ok (and possibly detect a bad OC?) in advance!
