Which version of Mepis are you running?
With Mepis 11, the easiest way to get newer Nvidia cards to work is by installing the proprietary Nvidia driver using the sgfxi script. See more about it here:
http://www.mepis.org/docs/en/index.php? ... 28sgfxi.29
Basically, you just intall the script, then follow the instructions on that page to run it, and it will download and install the latest Nvidia drivers for you.
For example, I've got an Nvidia GT 440 (relatively inexpensive "Fermi" based card that runs from PCIe Bus Power) with 1GB of GDDR5 that I use with Mepis 11 now. When I got it, I ran the sgfxi script and it downloaded and installed Nvidia Driver Version 285.05.09, which worked fine with it. I've since ran it again and updated the driver to Nvidia Version 290.10. Both driver versions support the Nvidia cards you're looking at.
Click on the middle tab for "Supported Products" on this page for Nvidia Driver Version 290.10 for Linux and you'll see the cards you're looking at (and you'll see the same cards listed under both the 32 bit and 64 bit driver versions):

sgfxi handles installing the latest driver for you automatically. Just note that sometimes you may need to run the script more than once. For example, when I upgraded from Nvidia 285.05.09 to 290.10, I had to reboot and run the sgfxi script again (the first run removed the old driver and the next run after a reboot installed the latest 290.10 driver). Running it more than once without a reboot didn't work for the update. But, running it again after a reboot intalled the latest driver version with no issues.
You can do the same thing with ATI video cards and integrated graphics chipsets (use the sgfxi script to download and install the latest accelerated driver). Again, you may need to run it more than once before it works (as it sounds like you tried it and ran into some issues the first time around). That's just a "quirk" with the way it works (sometimes needs running two or three times to complete removing the old driver and installing a newer once).
In any event, it sounds like you've got your existing ATI chipset working OK. But, for future reference, with Mepis 11, it's pretty easy to install the latest manufacturers' proprietary driver if desired by using the sgfxi script. So, if you don't see an nvidia or ati card model specifically listed as being supported on a Wiki page somewhere, just check to see if the latest video chipset manufacturer's linux driver supports it and use the sgfxi script to install the latest proprietary driver.
