They do ok @ 1920x1200 or 1080p, bf3 high/ultra pulls avg of ~50 on full 64 player maps, BUT afterburner reports only 75-80% usage which the 4670k will rectify.
Bf4 was pretty crappy, ~30 or so avg high settings, which the 4670k should also help with tremendously.
Basically I am gonna run the 460s with the 4670k and see how my fps improves. Then I will decide wether to go with a new card (and which one...like the price of the 770 but also like having a flagship card with the 780), or a new monitor first. I know ny 460s will choke on 1440p that's not even a question. But 500+ on a gpu makes me cringe.
Of course, I would have to spend more than 500 on sli 770 unless I scored a good eBay deal, and I woukd also be locked into sli again. Although, I have been EXTREMELY happy with the performance and scaling of my 460s. Just don't know if I want to go that route with 770s.
As far as what is more important...or what I "need" more lol, gpu is definitely priority over monitor. I just love the fact that I can get a 27" 1440p monitor for 370 bucks and I am really chomping at the bit to pounce on one.
