Hello my fellow pc brothers, i have a question for you all. When I first built my current build about six months ago, I decided to cheap out and use a gtx 750ti i found cheap on craigslist(about $60usd) just as a place holder until I was ready to upgrade. Well, I'm getting ready to upgrade since the 750ti has a difficult time running games at higher quality at 1080. I found a set of 2 gtx 770 4gb for $250usd used on craigslist. I was curious if it would be better to wait until pascal rolled out or if I should go ahead and jump on the sli 770s? I would have to upgrade my Psu to run sli 770s.
