hi everyone, I currently have two EVGA 680 4GB Classifieds in SLI but I'm seeing pretty low framerates in GTA V. I haven't really tested on any other game since I easily get over 60 on other games I have. but with SLI 680s I'm only getting 40fps on 1080p with textures on high, everything else on normal and MSAA on 2x I think. my single 780 on my media PC gets the same settings but 1440p...
I think the stock thermal paste on one of the cards could be going out and causing it to thermal throttle because when I run a synthetic benchmark like unigen, the top card will get to 95C and it's never done that before. there's a 2 PCI lane gap between the two cards with an internal fan blowing air directly over the cards from the front of the PC. the bottom card has normal temps.
I don't currently own screwdrivers small enough to disassemble my card so if its not the paste I'd rather not go through the trouble of trying to replace it.
also do you all think it would be more beneficial to get a third 680 Classified for around $300 used or to buy a second 780?
I could swap the SLI 680's with the single 780 I own and then add another 780 (3GB). or add another 4GB 680 (I have enough PCI-E lanes). I'm not sure which is better since I think more SLI decreases performance benefits? but the 680s are 4GB and the 780s are 3GB. thanks for and advice guys!
