Request for Experiences

Hi Folks.

A pro-bono customer of mine just called me up and let me know that he needs me to do a motherboard/uP swap for him; which will necessitate swaps of the memory and video card, because of motherboard architecture deltas from old to new.

So far, we've stayed with MSI and Matrox for MoBo and video card; however, this time around, his requirements have changed to include higher 3D frame rate performance, which Matrox just doesn't excel at, but nVidia does. Irritatingly...my direct experience with nVidia chipsets and Linux is nearly nil on the PCIe cards, so I'm trolling for your direct experience with SimplyMEPIS and nVidia chipset-sporting PCIe video cards.

So far, I've whittled-down my list of cards to choose from to the first 48 video cards (prices under $200.00) this NewEgg.com product listing but don't have much experience to fall-back upon with these specific products.

So, the favor I'm asking you for is this:
1.) Please look at this video card listing and consider the video cards having prices under $200.00.
2.) If you have any of the listed video cards working with a 6.0 or later release version of SimplyMEPIS, please tell me which video card you have and which version of SimplyMEPIS it is working with.
3.) If you found it necessary to secure drivers that were not included with the version of SimplyMEPIS that you are running, please mention that and, if possible, the origin of the driver code.
