I was going to get this card, but after finding out the cost I realized I would be better off getting two ASUS GTX 760's which are mini ITX cards. All this card is, is two GTX 760 GPU's on one card and each GPU has access to 2GB's of ram, which is why it is advertised as a 4GB card, and in effect it is already in SLI once you install the drivers.
Before I got my GTX 760's I had a pair of ASUS 2GB Radeon 7850's, the Radeon cards themselves were good, but the driver issues were something else, including daily display driver crashes, with no end in sight, and this all happened over the course of 15 months approximately. My GTX 760's don't give me any trouble at all hardware or driver wise.
See,there you could have 2 780's in SLI,so why would you want 2 of these? I think the pro's of the 780's would be greater with the 3 gb of ram.
Abomination lmao! That was funny.. Its a sweet card,just not for $649.. If it was $579,I think a lot of people would be all over it.
