Re: Wonder how well you PC will run Crysis
Essentially it looks like 8xAA is ~16% slower than 4xAA and 16xAA is ~4% slower than 8xAA, when not using trasperancy AA... Although it will vary a bit depending on the game and resolution.
They are not "free".
Also Xion you have SLI so maybe thats why it isn't showing the same results in your case.
