Need some upgrade advice 
Been playing Black Flag & BF4 bit lower than 4k (DSR/Resolution scaling)
Which has made me think i could jump to 4k
I been using Nvidia DSR @ 3880x1537 which is quite bit lower than 4k.
my question what do you think?
2 cards enough or tri-sli good enough for 4k?
do you think i should upgrade to x99 if i go three cards?
should i just go to 1440p?
should i just wait?
Currently got
i7 3770k @ 4.6 (can go higher)
MSi Mpower z77
16GB 1666mhz
2x 980 Stock
hx850w
Monitors
29134WM
SASA950D
Dell Studio 22" x2
