w*t*f people???. really??? a used 500 series? even a 560ti???.. Get a 660! this is 2012
, overclock it and get a 660ti's performance. When you sli these cards, you get better performance scaling with the 660's than the 580's. Trust me, i have looked everywhere to make sure i am making the right decision too, and now i have two 660's coming in the mail for 413$
.. There was a promo on newegg for the MSI 660 TF OC. But now it's sold out. The 660ti is just 5 fps faster on average.. -___-" http://www.anandtech.com/show/6276/nvidia-geforce-gtx-660-review-gk106-rounds-out-the-kepler-family/8
. You just need extra 29$!
Definitely add extra cash and get a 660... You can get another one later in sli, if you have a motherboard that supports it, and get 20-50% performance more than a single 680.
