I have this posted in several forums, because I dont know what is causing problem.

Hey Everybody,
First time here, hope you can help.
My system:
Asus A8n SLI deluxe
AMD 64 400+ 2.4 gig
OCZ DDR400 2 matched pairs total 4 gigs
Rosewell 600 watt dual 12v rail 19 amps each.
Evga 8800gt
Asus 24" wide screen 1900x1080
WD 130 gig raptor
HT/Omega sound card.
Win 7 Ult. 64

My main problem is that When I switched over to Win 7 my frame rate drop over half when I play WOW. I have tried several different drivers.Tweak force, Nivida Beta and current released, plus an older one that is in Win 7. Just cant get it to go up. I switch back to XP(on seperate drive) and its back to the high frame rate.
I am looking for several things. 1st what is causing the problem, Can I correct with what I have? If I need to replace parts, what should I replace and with what. I think my video card is ok. I use the system for WOW, Unreal Tourment 3, and the age of Empire series. Plus Digi Photography. I mainly play WOW. I like Nivida and AMD.
I have read it could be driver related or not enough CPU power and mem. WOW is a hog on the resources I am told.
Thanks in advance

Well, Its probably because XP has been around for 7+ years and that they have had time to actually make modifications, updates and hot fixes to the drivers for that particular graphics card, But because Windows 7 has just been released the drivers are still a little underdone and unstable.

you have an old low end rig designed for xp with a brand new os - dont expect miracles etc - upgrade your rig!

Windows 7 is a much heavier OS. So when u game you have that heavy OS running behind your game.
