[CentOS] Video Card

I want to be able to use a late-model video card with either Nvidia or ATI (AMD) chips that have the capability to use the GPU for numeric processing through the CUDA or AMD Stream SDKs.

I can't find any good source for hardware that really works under Linux, not to speak of Centos. I need a specific model and brand that a user has successfully been able to use the proprietary driver for under Linux.

I have tried EVGA Nvidia 9500 GT with no luck. I have also tried XFX 6300 XT (not CUDA-capable) and cannot make it work under Centos, either

I am using Centos 5.2, x86_64 on a Gigabyte mobo with Intel Core 2 Duo.

I appreciate any help,
