i agree with Jake. it's a killer rig, no doubt about it.
you might want to consider a faster 8gig kit of RAM. 16 gig is ridiculous for gaming only.
get some CL8 or CL7 RAM running at 1800mhz stuck.
is this the PSU you have choosen: Sea Sonic Platinum Series 1000 - Strømforsyning - Hardware - EDBpriser - find og sammenlign de bedste priser og tilbud på danmarks bedste prisguide
i know the site is in danish, but this PSU cost 2400kr (400$).
if thats the case: DONT BUY IT. too expensive for your needs.
by saving on the PSU and RAM, you might want to buy an extra 1TB harddrive and put those 2 in RAID0 for a speed bost on your data drive and double the space. you could also go for 2x 500GB harddrives and but them in RAID0 for a total of 1TB and save a little money if 2TB is too much space for you.
