My opinion:
I played this game a bit with my 7800GT and just upgraded to the 8800GT. Sure the game looks a little better now that I have things on medium and it runs better on medium then the 7800GT ran it on low, but for the most part it doesn't look very good still. And definetely not very much better either. Runs better, doesn't look much better.
COD4, and others changed dramatically. Bioshock, awesome. UT3, much better. World in Conflict is now playable woo hoo. Being able to play these games in all their glory is awesome.
It should be known that I'm playin on XP and thus, DX9 - but COD4 looks WAYYYY better then Crysis. Maybe I'll install Vista now on my other Raptor that is currently just sitting there and try it on DX10 - but I am not impressed with Crysis at all - graphics wise. Its still a fun game, but I expected a bigger difference overall with the 8800GT, and I know its the game not the video card because of how much better all of my other games look now.
I shouldn't need the craptasm that is vista and DX10 to get good graphics when other games are pulling way better graphics with DX9. How do people running it in DX10 feel?
