I have an I7-950 processor, Asus P6x58D-E motherboard, Zalman CNPS9900Max-B 135 mm cooler, 12 gig of G. Skill PL series RAM, Corsair 750 watt power supply. Will the Radeon R9 bottleneck with this set up? If so, any recommendations on CPU? I built this system in 2011 for PC Gaming but only played a few games and have grown tired of consoles lately and would like to get back into PC gaming but don't have a lot of money to spend.
