As I expected my local retailers are having trouble getting a Radeon distributor. I still have a few more to try and I am expecting their emails any time now.
If one of them can get a Radeon then I will get it. If they can't I'll have to get the MX because it would cost far to much for me to import a Radeon from the U.S.
The MX isn't a bad card but I would prefer to get a Radeon. If I can't I'll be a little bit disappointed.
Anyway, thanks for your replies guys.
