I am going to try to find some answers online-- and have PM'ed Aww_3_3
who is much more familiar with the gamer hardware / SLI stuff than I am.
As I said earlier... I'm no gamer. Too old and slow.
Vista -- in particular is not particularly popular-- despite it having DX 10 and all that...the drivers from the major-makers just have not caught up with it's quirks yet.

Alright, but why am i not getting the right frames per second, I used to get 100+ fps in css and bf2. Now i get 25-50 fps. its being capped by something. I did sli still no change. I bought 9600 gt oc instead still no change. And higher and better Power Supply Unit still. For more info on the prob its at the end of my first post.

The whole SLI thing... to MY knowledge... is based on dual video cards. As far as I know-- SLI does not work for single units.
That card is pretty well reviewed-- but for true SLI you need 2 of them

Yessir-- what I'm trying to say is, that you either have a driver problem, or a software problem.
Stop throwing money at it (please)-- you will go broke-- and it probably still won't be fixed.
I went back and reread some of your original posts about bad FPS--
and it feels to me-- like a conflict- or a bad driver.
I am trying to get other help for you-- as I don't run Vista-- makes a big difference trying to troubleshoot an OS you have never run.
