What are the chances

[GundamSonicZeroX]

I mean, I have a GeForce 7900 GT KO not superclocked at 610/905 without voltmodding it. Let's say I hit 700/950 with a volt mod (that's reasonable to me). And later I get another and put them in SLI. What are the chances that I would have to put my current clocks down? And what is with reviewing sites and image comparisons? They all look ugly unless they use like 16x AF. The surfaces will look real jaggy. I'd get a pic but I'm on a school comp and I'm almost outta time.
