Differences between ATI and nVidia these days?

[Zaphrod]

Hey all,

I am currently planning on buying an ATI 4890 but have only owned nVidia cards for quite a few years. The last ATI I had was a Radeon 9700 Pro. I am wondering what the differences are in terms of features and extras other than the gaming speed and what modern and frequently updated programs there are for ATI cards for tweaking etc. Also do they currently work with Windows 7 and what is the driver support like for Windows 7, I mean I have looked and they appear to be available but how well do they work? Also when I did have the ATI the actual 2d and 3d image quality was always a little better than the nVidia, is this still true?

Sorry, I am guessing you guys posted without reading what I actually wrote I am not looking for what people think is the best I am looking for what type of software exists for ATI that is comparable to what is used for nvidia such as OCing and tweaking tools as well as other programs or features that ATI has that are useful.

Sorry I didn't mean to open a can of worms and in hindsight I could have worded the title differently as many seem to be replying to the title rather than my post. I need to be clear I have already decided to go with ATI.

TheRealDeal - Thanks that is the kind of info I was looking for, does the catalyst control centre let you set up profiles for games etc?

Anyone have experience with ATI on Windows7 64bit? How are the drivers at this point?

I don't really need to know what features nVidia might have that ATI doesn't but I would be interested in useful features ATI might have that I am not aware of having used nVidia for the last 4 years.
