I'm looking for a video card setup to power a 5760x1080 triple monitor setup. I have a single 2560x1440 monitor that I will use solo for maybe 1/3 of the games I play.
Which would be a better choice - an EVGA GTX 780 w/ ACX cooler (1020 MHz boost clock) for $660 <OR> an EVGA GTX 690 (1019 boost clock) for $790?
It seems like the GTX 690 definitely gets better performance but quad-SLI appears to have diminishing returns. I'm also concerned about the longevity of the 690 with the effective 2gb memory, particularly at the 5760x1080 resolution - if the memory proves to be a cap, I can only sell the 690 and start anew whereas insufficient performance from the 780 could be remedied by simply purchasing another card somewhere down the line.
Any help/information would be greatly appreciated!
