Hello all. I recently built my personal rig: i7 3770k, EVGA GTX 670, 16GB G.Skill Sniper RAM, 750GB HDD, Corsair CX750M, ASRock Z77 Extreme4 LGA 1155, All packed inside a Corsair C70 White. I love it compared to my old one. is mah bb. But it's not really performing like I expected. I currently play Planetside 2/Borderlands 2/CSS for the most part... I see constant drops in PS2 down to low 30's, which is sooo lagggyyyyyy >_< even on all settings turned to medium and motion blur off, It stays the same. I was really hoping to never go below 40. PhysX isn't a huge deal for me. It's nice but whatevah. Should I return my 670 and get the similarly priced 7970 before it's too late? Thanks.
