It already has, Raa'Torh. I bought an ATI Radeon 9800 Pro 128MB DDR from CompUSA for $250 USD two Sundays ago. Awesome card, can't run the latest and greatest at max speed but its playable. FSO runs great, but suffers from all the performance problems associated with it, including massive texture load. Some of these days I'm going to go into my VP file and make all the sizes of the textures multiples of 2 because I am too impatient to wait for the community to do it for me
The Radeon 9800XT 256MB is holding the title of "ATI's current $400+ buck card". If you wanna wait for THAT monster to drop in price, you may have a long wait.
If you do get an ATI Radeon 9800 Pro, don't install the CD at all, just go to ATI's website and download the latest Catalyst drivers to be hummin right along.
Your mileage may vary.
P.S. My Anti-Aliasing doesn't work with FSO. If you adore your AA your gonna have to lobby the SCP team to fix Radeon AA support with FSO, because I have tried EVERYTHING I know to fix AA and NONE of it works!
