Anyone have one of these? Thinking of grabbing one from newegg: http://www.newegg.com/Product/Produc...82E16814130787 Is it a good deal? Should I wait for cyber monday/week and black friday? Is there a big difference between 660ti, 670, and 670ftw? Are the price increases justifiable/worth it? Looking to get me a card that will hopefully last around 3+ years the more the better.
