Would the gtx 570 2.5gb vram card run crysis with the dx11 high res textures better?

basically i want to know, if i used a gtx 570 sli with 2.5 over the origional 1.2 will i see an increase in framerate or not? if so, will it be significant? or does anyone have a chart of crysis running speeds with and without the dx11 on?Would the gtx 570 2.5gb vram card run crysis with the dx11 high res textures better?
Having the 2.5gb model vs 1.2gb will not affect framerates, unless you're running at 2560x1600 or with dual monitors at 1920x1080.



Original Crysis does not support DX11. Crytek released DX11 and high-res texture patches for Crysis 2, which make it look better but slows things down. Lots of forum discussion about that.
