PC Case Gear has the Leadtek GTX 680 on sale, normally $519 whilst stocks last. I checked prices on statice and PCCG was the cheapest price with its original price of $519. Decent savings of $40 bucks!
Features a 2 year warranty as well.
Product specifications all on the website link provided.
the last time i spent $600 on a video card, that was on a measly 6800gt…on release week…never again. I felt like an idiot afterwards, though it did lasted me few years.
