Default Re: Where are the GeForce GT 240 Linux drivers?

I replaced a GeForce 7600 with a GT 240-based card in my system yesterday. Normally, I'm using 64-bit Fedora 12 as a MythTV backend and VMware work area. I had been using the nouveau drivers and things seemed to work OK to this point, but I'd been interested in seeing what the NVidia drivers could do with a new card. I'd seed this thread and decided to watch to see how things worked out before switching.

Last night, I realized I had an old installation of UbuntuStudio installed on a test partition with the Nvidia drivers installed so I could check things out. In the categorization of hardware / software / performance, I'd summarize:

Zotac GT 240 / DDR3 / Passive Cooling
64-bit 2.6.31-9-rt kernel / X-server 1.6.4 / Nvidia 185.18.36
PowerMizer runs card at highest perf level (level 2) @ 550 / 790 with glxgears running
Side note: GPU thermal monitor show stable 50 C as I type this

Don't know if this is helpful, but it did seem like another data point.
