I thinking of getting a new pc. what I have now is

i7 920 @3.7
6 gigs ram @ 1366 I think
gtx 760 4 gig

I have been an Asus fan but I like the.

ASRock X99 OC Formula LGA 2011-v3 Intel X99

Intel Core i7-5820K Haswell-E 6-Core 3.3GHz

G.SKILL Ripjaws 4 series 16GB (4 x 4GB) 288-Pin DDR4 SDRAM DDR4 2666 (PC4-21300) Desktop Memory Model F4-2666C15Q-16GRR ..

I was think about
getting a gtx 970 4 gig . but with the memory scam with that I think ill wait.

what I would like is some input on. if I just replace the cpu main board and ram with the list above
will I see any gaming increase or do I need a better video card for that?

with some of the games I am noticing I cant have everything maxed out witch is a must have for me :-)

I play on a 65in tv @ 1080p. the only other thing this pc is used for is watching Netflix .

thanks for your time and thoughts
