Which brand Radeon 9600 is better?
 

If you're in the UK try 9800 pro www.overclockers.co.uk (£107.50) or
9700 pro from scan.co.uk (£102.50)

For games you want a 9600Pro or better. The 9600SE won't make much of
a difference with your current one.

Yes, and the 9600xt attains performance that is equalled by an overclocked 9600 Pro, so
save you money and buy the latter.
