I've been using two gtx 275's in sli on a single 1080p monitor for the longest time and i am looking to upgrade to surround for the first time. There are a few options as far as gpus go, but i'm trying not to break the bank while doing so:
(including tax)
used 590 evga classified for $500
new 670sli $1000+
new 580sli $768
used asus Matrix GTX580 Platinum sli $750
used 3gb 580sli - $800
new 680 4 gb $670
As for price i'd like to keep it under $600 if possible. Any sujestions.
