Hey guys , I am currently having Ubuntu 11.04 in my lappy and I feels like alot of apps doesnt support this OS. So I decided to convert back to 10.04 LTS.

I visit the site http://releases.ubuntu.com/lucid/ . Wondering which one shud I choose. My lappy is Compaq Presario CQ40-420AU AMD TurionX2 64 proc.. Shud I choose AMD 64 or Intel x86 for better performance ?
