Hey guys, I've been running my 680 GTX 2Go since it's been shipped and I'm pretty happy with it. I'm thinking about moving to a surround gaming setup and therefore add a second 680 to maintain proper gaming experience. First of all, I'd like to know if the current drivers are good enough with SLI. I mean no/low stutter, incompatibility, artifacts, crashes and so on. Did you guys have trouble somehow? I mainly play racing games such as DIRT3, Shift2 and F1 2011, but also some action-RPG like Diablo 3 (needs high spec with AO and massive AA) or Skyrim/Darsiders 2/Witcher 2. In addition, I have "only" 2 Go of VRAM on my current card. It is going to be a problem when moving to much higher resolution? 4Go cards are pretty expensive and I would have to sell my current one Finally, should I update my PSU for something with more horse power? I have my CPU overclocked (check my profile on the left). If yes, do you have any pieces of advice with ~150/200€ max (I live in France)? Maybe the Cooler Master Silent Pro M2: http://www.guru3d.com/article/cooler-master-silent-pro-m2-1000w-psu-review/8 Any feedback will be much appreciated! Regards.
