To fix or not to Fix

I just got a new comp I love it, lol but thats another story, now for the big ohhhhh… Its ATI, it has the ATI radeon Xpress 200 Chipset on the mother board, I could go to Nvidia, but with ATI i can do surround view with a graphics card that i want to buy and will be able to soon. I know that i could switch over but i don’t want to im wondering if anyone has found a fix for the lag on this chipset. i have tried the atioglxx.dll in the blender directory, it helped alil but it still goes slower after couple of minutes. I was just wondering if anyone has found a fix for this chipset if anyone has please let me know also any help would be appreciated.

P.S. i also don’t want to start the ATI vs Nvidia bias conversations, just help or switch is all i need.
