I don't know why I didn't post this earlier oOo: Anyway, if there are any Radeon 9500 (the non-pro card) or 9800se owners out there you should try out the softmodded drivers from
http://softmod.ocfaq.com/ It's a bit hit and miss in that only some cards are able to softmod, but if you're one of the lucky ones your 9500 will perform like a 9700, and your 9800se will perform like a 9800/9800pro. More details here:
