ATI have dropped support for your graphics card as of February (in windows too), so if you need wow at best fps, you need to stick with felicia for now. Keep checking out the next versions when released though, to check for improvements to the opensource driver, e.g. Mint 8 Helena this autumn. If the worst comes to the worst, mint 9 is likely to be LTS (and available just as felicia loses support), and with another year of development on the driver, is likely to perform much better than it does now.
