Do Ubuntu 13.04 support ATI Radeon 7750 Graphics Card?

The last Catalyst driver release for linux with 77xx series support states that it is compatible with 12.10 (released on 24.04.2013)

I am going to buy the graphics card before finally setting up my desktop with new SSD(64gb)+ new 1.5tb HDD+ new GPU and top of all new OS i.e. Ubuntu(moving from Windows completely). So I need to know the obstacles I may be facing.

As some other topic about 7750 GPU stated, someone could manage to make it work by downgrading the OS and then upgrading while keeping the older drivers! Can that be an option?

Btw, some people seems to be anxious to mention how Nvidia supports are better for Linux in the forum. But I find the benchmark and prices are much more user friendly with ATI cards.
