I would go with max on that, very good parts, quite expensive though,
good pick on the i5 over i7
Very high PSU you have there, if you want to cheapen your build a bit, buy 650W
Your case looks good too, but it can also be cheaper if you wish
Rest of the parts are fine to me, very nice build, will run those games like a breeze
EDIT=if you don't want to overclock your CPU, get the non-K version, they are usually cheaper.
