normal optical drive, win 7 64 bit, SSD
so yeah 1. is it balanced and 2. can it run games like BF3 @ ultra settings with a good framerate
get the K version for a little more. for drop to the i5 and get the k version. there is a minor issue hyper threading lowering perf. Memory is overkill but CL8 is good. get the winforce x3 in perference to the x2, i'm seeing both of them at the same price regularly.
