Hey guys, I'm building my first desktop rig for gaming. I currently have an i5-4670K CPU, ASUS Z87-A Mobo, Corsair Vengeance RAM 8GB (2x4), Corsair Carbide Series 200R Case, Corsair CX600M PSU, and a 1 TB Seagate HDD (7200 RPM). After much debating and running my budget over and over again, I've decided to go with the EVGA GeForce GTX 760 SC/ACX Cooling. Now I'm aiming for everything in here to last me for about 3 years or so of gaming. I do have a couple of questions though; 1) Would my CPU bottleneck an SLI configuration of that GPU? (I know I will have to up my PSU to at least 750watts, but I'm not planning on doing SLI until maybe a year and a half in. When the 8xx series are released) and 2) Do you think SLI'ed 760's will be able to compete with the high end 8xx series? (I know it's mostly an opinionated question since those cards are a long ways off, but I want some insight from people who know PC's a lot better than me.)
