Driver help! Vista 64bit - 7600 GS (nvidia)

After poking around here I've noticed a few people talkin about optimized drivers.

So yeah, as the subject says.

I'm currently using Vista 64bit and a GeForce 7600 GS - 512 Megs RAM(I want to upgrade. I do!)

I'm wondering if there are any drivers that'll work better then the "normal" ones.

I have 2 monitors at the moment (finally got the widescreen)

Acer P221W (22in widescreen)
ViewSonic G90fb (19in CRT)

I currently am using the 19 in to run things in window mode.

Just wondering if there's a better way to do it, and mainly some better drivers.

I get about 30 FPS even on my solo set up.

2 Gigs RAM
Intel Core2Duo 2.4 Ghz
GeForce 7600 GS - 512 Megs RAM
--Edit2: I can't count my RAM right. :)

I've tried running WoW at a bunch of different resolutions and before I would get 50+. Now I get about 30 +/- .


I seen someone mention Guru3D and I did a few google searches, but I'm not sure what I'm really lookin at. Everyone here's pretty knowledgeable when it comes to this kind of thing it seems. :)

/Ramble off


Edit:

I just downloaded the newest from the nVidia site. They just came out with new ones on 12/20 (4 days ago) maybe i'll see a difference. :)
