How to reach 4x SSAA + on my rig 1080p , should I SLI gtx970

[m4r1n7]

Ok folks, let me ask you something.
I want to make sure to get 1080 p 4x+ SSAA gaming performance with ultra settings
so I want to SLI 970x

my rig now is:

Motherboard: Asus Maximus VII HERO
SSD 120gb KINGSTON hyper
COOLER: Coolermaster gts v8
CPU: i7 4790K 4.0ghz TB:4.4 ghz
Memory: 16 gb Ripjaws 1666mhz
PSU: TX750 corsair
GPU: Asus Strix Gtx 970 4gb
MOUSE: Razer Naga Molten
Keyboard: Razer Anansi
Headset: Diablo III SteelSeries

Should I OC cpu or gpu or get SLI gtx 970 to run smooth 4x ssaa on new games like shadow of mordor, Witcher 3 etc.. or is that a overkill for 1080 p monitor (1920x 1080 res)..cause right now with this rig I cannot reach smooth gaming with 2x 4x ssaa on tomb raider or games like that , I get 40 -50 fps max with vsync (playing with that always), and it feels stuttering a bit ,

so I want max out everything and playing smoothly on 60fps..
if is that a possible thing to get.

and If I get another gtx 970, is PSU of 750 w enough for my rig with that 2 graphic cards in it.

thank you!

I would get over running everything completely maxed out their very little difference in Ultra and High.
I run SLI 970's on 3 X 1080p monitors and everything runs fine for me on high settings.
To answer your question yes your power supply can run 2 970's

okay but yea Iam playing also smooth on ultra high details now but without any score of SSAA
so thats why I want to SLI 970gtx , then I will get smooth 60fps or not?

High levels of AA are literally pointless to run. You can't tell the difference in the majority of games which just makes it weigh down your computer. Tests done by Nvidia on far cry 4:

Far Cry 4 max AA (8x MSAA):

Far Cry 4 no AA:

Performance hit:

^^^^^^^^^^^ All of this their no difference so why spend the money.

Well there is a difference with the edges actually
yea I know its not that easy to spot but believe me if you are person like me you see everything xD
kinda perfectionist xD

I want everything to be nice and smooth
thats why Iam asking if I can afford one more gtx 970 could I run it smooth then with 4x +AA on 1080 p
