Upgraded graphics card/same performance

[monsterinc]

My system,
Intel e8400
Ram: 3GB
Motherboard: G31M-S2L
Video card: 8800gt 512MB then upgraded to 260GTX 896MB

The problem is that I have the same or less FPS on the same games at the same settings.
It constantly lags freezing for a second at some points. This never happened to the old 8800gt though.

When I removed the old 8800 i switched to the integrated video then after a week I installed the new 260GTX and removed the Integrated video and installed the new one.
But I didn't find the old 8800 driver on device manager even with Show Hidden Drivers.
I also used Driver Cleaner Pro. Every software detects the new 260GTX but I am not satisfied with the FPS with some games. For example in crysis i had 50fps average constantly on med settings. Now I have ~50fps then drops to 30fps.

I think the old driver is conflicting with the new one. Any advice on what to do?

It really sounds like your power supply is not putting out enough power for that GTX260.
What is your Power Supply?

The 8800GT and the GTX 260 use the same drivers.

i agree psu needs more juice!

I was under the impression that if the card doesnt get enough power the cards LED would turn red and not work at all. Id recomend making sure you deleted the old drivers correctly with Add remove and downloading the newest drives for the GTX 200 series and see how that goes

nah... for one the gtx260 doesnt have any leds... and depending on the PSU, it will run ok in 2d, but will barely be able to render 3d.

Can we see your total system specs? Maybe a cpuz screenshot? If your old card and your new card perform the same, that tells us that we have a bottleneck going on somewhere else. 3gb of what type of ram? What kind of hard drive?

Microstutter can be very annoying for sure.

An underpowered PSU will generally cause a system crash, not a slow down(although stranger things have happened).
