got my new system done (after more than 1 year into it) and been playing F1 2012, Dirt 3 and some Black Ops (which i don't like to be honest).
i'm at 3.85GHz CPU (i7 950 22 x 175), QPI at 7.9GHz (44 x 175) DDR3 1600 7-7-7-20 1T o/c to 1750MHz and 2xGTX680 SLI all over 3 x 27'' LCDs and with bezel correction resolution comes to 5948x1080 (5760x1080). Play everything full or max and doesn't miss a beat. I had it at 182MHz clock (so CPU at 4GHz and memory 1820) but had some blue screen issues and throttled down a bit, need to replace the radiator fans as the current ones have poor static pressure - i got replacements but i'm too lazy to drain the coolant just for a few MHz, might do it if i have a problem but so far no hiccups.
I might try FarCry 3 if there's a demo, if not when i'm done with the other games I might spend the money on it.
Anyone tried RFactor2 ? - i was thinking of getting it but i heard people complaining (it's still in beta but you have to pay boo), probably will wait till some solid mods come out as apparently the selection is poor right now.
