I wouldn't get a 690. Here is my 2 cents. I would say you may be better off getting two GTX670's with 4 gigabytes of ram and putting them in SLi. That or perhaps wait for Titan or even possibly the next series of GPU's coming out sometime in q'2. I've heard with a 690 that the ram is split in 2 so its not really 4 gigabytes usable ram.
