i will advice you go with the ti version instead of non ti because of its downgraded shaders and memory clock.
you can max out crysis with that rig 30+ but 560ti will be a worthy upgrade rather than 560.
i think just go with the hd 6870 as 560(non ti) is just equal to it in most of the cases and you can always sli in future. http://ncix.com/products/?sku=56262&vpn=HD687AZNFC&manu...
it depends on resolution. if you want to play crysis 2 with the dx 11 patch at max settings at 1080p you need something like a gtx 570. with your rig you could probably tone down a few of the trivial settings to get good performance at still great looking visuals.
Not only does this build come out cheaper than what you have up above, you end up with a motherboard that over clocks higher than that Asus board, you get a better vid card, and better psu. That particular model of Corsair you have up there is made by CWT and not Seasonic like the upper tier Corsair models. This XFX psu down below is a single rail psu manufactured by Seasonic for XFX.
