I am looking to build a 4k gaming rig. I plan on either:
A. Getting two gtx 770 for ~$300 each and getting a third later on
B. Getting two 7990's for ~$300 each, better performance, no upgrade ability
C. getting 4 7970's for ~ $140 each, basically same as B but multiple cards
So my question is, Will 4 7970's / 2 7990's be enough for 4k, or will I need 3 770's (more $) or I suppose I could even go as far as getting 2x 780's, but will 2x 780's actually be better than 3 770s or 4 7970s? thanks!!
also is 1000W psu enough? 4770k, 2 ram, one ssd, and up to 4 7970's?
