CentOS 5 works fine, but we haven't done any sufficient CentOS 6 testing because other software vendors in Engineering are still not certified for the platform. What kind of problems are you having? Perhaps some of our findings will still apply. >> > > YES!

The price for the graphic adapter was not an issue at all. Finding one that works correctly with the software is another story. The newest Ati driver worked only once! After every session the workstation had to be rebooted to get it to work again. I went over to Cento6 just a couple of weeks ago. Most workstations now work with the standard Nouveau driver. No problem seen yet. The only annoying problem is that sometimes an application windows stays "empty". Simply resizing the window fixes it. for me it's hard to say what causes. The software needs backing-store on the X server being enabled. I underdstand this is old technology and I suspect this is now causing problems. But the bottomline for us is that CentOS6 seems to be easier with the built-in drivers compared to CentOS5.
