For the vintage or budget buyer, here are a pair of Nvidia GTX 690 gpus. These were pulled from a surplus system I picked up at UoW- Go Huskies! They are very clean for their age so I am guessing they were at least reasonably cared for and maintained. I did not repaste them, but I did bench them on furmark and they worked fine. They need a repaste for sure. These cards are unique in that they basically have two sets of GPUs and memory on each card, so each card will show as 2x 2GB GTX 690, the pair will show as 4x, so all together 4 GPU chips and 8GB worth of vram. They can be used separately, but they were designed to be used as a pair for quad SLI setups using a SLI bridge. Both work well, the fans feel and sound good. There are some minor swirl marks on the clear plastic, and some minor discoloration from age. Please look at pictures to verify condition.

These cards run driver version 461.92 I believe. They take 2x 8pin power (each).

Update: I did set them up with sli, and it works, but the best I managed to get was 3way sli plus phys x. Not sure I had enough pci lanes on my mb? Anywho, you can be the lucky one to sort that out :)
