So I realized today that I'm running DirectX 9.0c on my iMac Alum. 20"/Radeon 2600XT, running XP SP2. Anyway, I've heard that DirectX 10.0 is out, so I'm wondering if it would negatively afffect my gaming at the least bit? If it does it at least some good, then I want it, but if its really pointless, or whatever, I would like to know. Thanks.
