Sky is the best, but it hasn't improved since Doom.
Water is the worst I've seen, it's totally unrealistic.
Fire is greating PRETTY close to real.
Aircraft and weapons are good, too. Characters are off by a bit.
MX is substantially slower than regular and because of those fewer pipelines those same number of features probably just bog the thing down. I mean it works great, who needs some $600 graphics card unless they want to render Toy Story in real time. I say MX is pretty good and usually the way to go. The Ultra and normal are unreasonably expensive because Nvidia thinks they have a monopoly, but Radeon is faster in a couple games and only slightly behind in others. I prefer radeon because it uses technology to go faster instead of brute force higher clock speeds, which means Radeon is cooler and uses less power. But I'm thinking from a laptop perspective, mostly.
