personally I'm not a fan of the omegas. I know people have good luck with them, and they did seems to run fine, but they are based on the cats anyhow and I just don't like the Radlinker interface. I installed the Cat 4.9's without the control center, then I put in the beta of the 4.10 hotfix, and they run fine with all the ati options. I know that doesn't help you much but as I said I just don't like the Omega interface and control panel. good luck to you
