a single 780? no except for a few odd cases from poorly optimized games or the 1 or 2 games that actually utilize HT with 4 cores. 780 sli at 1920 it would maybe in a few more cases but your cpu is about as fast as it gets.
that's good to hear, but honestly now that I think about it, I would need a new case, psu and if I wanted a better gaming experience a 1440p monitor. Not to mention I don't even have an ssd... My 7870 has been able to max out games at 1080p no aa with no issues so far, so what would be the point?
Maybe I will just hold off on it until my pc and my body is ready.
