New Gaming Build (~$ 1,400)

looks good but id get the xfx 750 watt ps instead rest looks good

Good build. One suggestion. Get the 4GB 770 instead of the 2GB. Present games easily use 3GB of ram so you'll be wanting the 4GB is one to two years.

well some games use more than 2gbs in 1440p but def if u can afford 4 gigs would be more futureproof

IF you are gonna do alot of multi tasking i would go for the fx 8350 or even fx 9590... They are very good chips, they are better for multitasking and i think the newer games will start to utilize more cores. Also the R9 280x is much better card than the 770.
