[SOLVED] Gtx 460 bottleneck?

[KirbStomp]

Hello,

I recently upgraded my video card from a Radeon HD 5450 (512 MB) to an Nvidia GTX 460 (768 MB), and now a few games, specifically NFS Most Wanted and Doomsday Engine now run at really crappy framerates, even on lowest settings. I'm running on the most recent driver for the 460. Both games ran at full framerate on my old 5450.

System specs:
AMD Phenom II x4 965 Black Edition
Asus M4A79XTD Evo motherboard
4 GB and 2GB DDR3 Patriot memory modules 1333 MHz
Coolmax V-600 power supply (600 W rated)
Asus ENGTX-460 768 MB
Windows 7 Ultimate SP1 64-bit

have you tried clean driver install?

Thank you, that seems to have solved the problem. I installed the driver yesterday, but when I went to reinstall it, Nvidia's auto-detect plugin showed my driver as being version 03.04.
