i've already install my SCDA and complete..
but the problem is when it detect my system. it say that i can't run it in minimum performance.
it is because the driver version 6921 (X). so what driver version i should have. i've already dowload driver from nvidia but the driver version still 6921. where i can have it..

for info :
proc e6550 2.33
mem 2 gigz
vga geforce 8600 gt 512mb
win xp sp 2

you can find and download your drivers here:
http://www.nvidia.com/Download/index.aspx?lang=en-us
just fill out the fields, press search, download, install and reboot. piece of cake
