Highest performing ATi Drivers

[xSteathx]

I did some searching, but I am not really uneducated on todays drivers and whatnot that I wont know what to do.

I recently lost a x800xt =( (it died). So I am back with the 9800pro. I currently play CS:S and WOW, I play CSS with recommended settings and frames still get low. Looking for an ATI driver or omega or whatever kind their is out their that will maximize performance, IQ I really don't care about.

System Specs:
XP Pro 64x
AMD Athlon 64 X2 4800+
Corsair PC2-6400 (400MHz 5-5-5-18-22)
Radeon 9800 Pro 455,378 OCed
(Crappy mobo that doesn't really support or worth OC ram CPU)

And I am about to buy CC3, and that game looks like it will kill my card, so anything that will help performance will help a lot.

I think 5.12 are the best for the 9X's cards, and 6.12 for X8's cards

6.11 + ati tray tools is the best for my x1900xtx
