I doubt the processor will bottleneck the cards that much, it's quad core, with H/T (rumored to be liked by f4), so.. hard to say, i'm having a similar debate with my system. 2011 is at end of life, but in reality, short of spending thousands of dollars on something that will be current for another year? not worth it. but at this point, i don't need 4k gaming. i have a 980ti, 16g of ram, ssd drive. i'm good to go until we see the next round of whatever upgrades come out. give it a year.
