I recently finished purchasing all of the necessary parts to build my first custom PC. Newegg had a sale for 30$ off on the 770 at the time, making it a relatively small jump from the 760 I was eyeballing to the 770. After reading many of the reviews, I even forked over a substantial 50$ or so to upgrade from 2gbs to 4gbs FTW edition, in the name of future-proofing.
Despite all that, the literal moment I finish buying all the parts, ex. the graphics card, the 780 FTW edition goes on sale for 45$ off. Now I'm wondering if I shouldn't quickly send back the card while I still have the option for a refund, and buy the 780 FTW while it's on sale.
I understand I'm gaining more cuda cores and the advanced 384-bit BUS on the 780, but I really am unsure just how much of a performance upgrade that is in the real world- again, this is my first time building a pc.
So, experts on this site that have already helped so much, as well as those who choose to skip to the point-
Which should I choose? The 770 or the 780? I don't plan on running SLI anytime soon, but I will have a PSU capable of running either or if I buy a second sometime down the road.
