Anti-aliasing on ATI

Question--

I am currently using a GeForce 8800GTX. One of its best features is the use of anti-aliasing modes that have only a negligible performance impact. For example, I can easily run 16xCSAA anti-aliasing in Team Fortress 2 and other games. In most games, I can run 8x anti-aliasing. Revisiting old games like Half-Life 2, the image quality is pretty astounding.

My question is, assuming I want to maintain high levels of anti-aliasing but switch to AMD, does AMD offer the same sort of anti-aliasing performance. I briefly owned a 2900XT and returned it after discovering that its higher anti-aliasing settings actually blurred the image (tent filters, ect?) Are they still using that system?

In other words, is the anti-aliasing better on Nvidia? What if any compromise am I making if I switch to say, a 4870 or 4870X2.
 
ATI has completely fixed Anti-Aliasing. In fact, it scales better then Nvidia's. (At least, NV's last gen., not sure about 200 series, but I'd imagine they loose around the same percentage)
 
If you use in-game options, there shouldn't be any texture-blur. That's only for wide-tent AA, which may have been fixed on this newer series of cards - I can't say for certain, though.
 
There is never any blur unless you used wide or narrow tent options.

Apparently there is a new "special AA" mode in this series called "edge" AA. I would assume that wouldn't blur the entire screen like wide and narrow tent do .
 
AA should scale better of the 4800 series cards than on Nvidia's. Unless you select wide or narrow tent you won't have any blur. 4/8xAA with edge detect is probably the best way to go as far as image quality. The edge detect was introduced when the 3k series and might have been available on the 2900's.
 
With 4850 CF you can run 16x REAL AA. Negligible performance hit in most games I should add.
