Will go to ultra with gtx750ti and camd fx 6300 8gb ram. (Assassin's Creed: Syndicate)

funny, but no, not funny. of course it won't. on my i7 3770-gtx 970 it went to ultra with 20 fps, with shadows at high 45-55 fps

With a resolution of 1280 x 1024

Although how much fps?
And anti-aliasing msaa2 + fxaa
AND shadows averages and light ssaao

where to throw off the money for treatment?

And the shadows are middle and the light is ssaao

You are sick ? No seriously ?! You really think that the fly, the elephant will carry. Well, you understand my metaphor))) Answer: No, you can not even count on 10 fps on such a trough, play strictly at medium-high (And not 60 fps).

Textures maximum
rendering very high
light ssao
shadows medium
anti-aliasing msaa + fxaa

Rusik is
even on my i7-3770k, gtx 680.16G ram was running at high 50 fps without shadows)

see no reason to be surprised

980 to this processor for more memory. then it will go under 50 fps with overclocking chain.

Are you kidding? Medium High? Minimum. And maybe even lower, cut through the configs.
