Just bought a 9600 gt a month ago And it performed Lousier than
my 8400 On audiitionsea. First suspected that its an psu problem
And changed it But the Problems Exist .. FPS is not stable

Specs :
Compaq SR5385CF
Intel core 2 Quad Q6600 @ 2.4 GHZ
4gb DDR2 RAM
250 GB HDD
9600 GT 512 MB
installed and reinstalled almost all drivers versions from
nvidia
What is your new PSU?
Also, download GPU-Z and check what it says under "Link
width". Make sure it reads something like PCI-Express x16 @ x16,
not PCI-Express x16 @ x1.
I had the same problem when I first installed my new
graphics card, so these I the steps I took.
If it displays PCI-Express x16 @ x1, switch off your computer,
remove the power cord and any other cord attached to the computer,
open the casing and remove the video card. Press and hold the power
button for about 10 seconds.Next, reinstall the video card back
into the slot, connect the power cable into the graphics card. Put
the cover back on, and wire the computer up. Boot up, and check
GPU-Z again. It should display PCI-Express x16 @ x16 now, or you
will have to reseat the card again.
