I was thinking... I just bought the GTX 780 Ti bad ass card hands down but games like Watch Dogs and others sluggishly using more then 3.5 vram is a big problem. I can return it get my money back and get GTX 770 4GB OC it and run as fast as GTX 780 at 1080P or faster at 1440P I'm holding off for the 2nd batch of nvidia's 9 series GTX 980 I know they will have 4GB and be faster than a GTX 780 but there's talk going around about later in the year or next releasing a model with 8gb and custom cooling maybe even a GTX 980 Ti 8Gb.
