I just recently purchased a GTX 680 for around $520 right away since I saw it on sale and thought I'd pounce on it while it was there. Sold out 5 minutes after I placed my order. Now I'm feeling a bit remorse since before I was contemplating going with a 7970 for about $70 cheaper. I plan to do surround/eyefinity gaming in the near future. I was also considering 7850 xfire or a 7950. Any opinions on the matter?
