Summary: I bought 2 of these 4 Gig cards delivered for under $325 each. What a steal. This is an excellent video card, As a matter of fact I actually replaced an MSI twin Freeze GTX 680 2 Gig Card with this card, because I am running 3 Asus 2560 x 1440 monitors, and the GTX 680 2 Gig card seemed to be a bit overloaded. Not this card. It handles the monitors fine, and the displays were already extended upon boot into Windows 8.
The best bang for buck for extended resolutions, period.

Summary: If you plan to use multi-monitor or extended resolutions (i.e. 5760x1080, 2550x1440, etc) and like to use lots of AA and high res textures, you might want to consider getting a 4GB GTX 670 instead of a 2GB one. And, since Zotac used the reference 680 PCB here it is a lot higher quality than similar offerings by other brands. I have three of them in back-to-back SLI and highly recommend this card - quiet and cool yet a performance monster!!
Summary: An excellent card, capable, fast and relatively quiet. With the 4gb of GDDR5 Vram it performs brilliantly in games such as Skyrim and GTA IV when using very high resolution texture replacements, where a 2gb card would perhaps suffer. As for the review slagging it off with what sounds to be a faulty card/motherboard or even an installation error. Why rate so low, when you could have returned it and got a replacement?
Summary: I bought this when it was £279.99. Good preforming card running faster than a regular GTX 670. Probably matches a regular 680's preformance. Loving the 5 year warranty also but make sure you sign up for this with Zotac within 14 days.
