Re: Best distro for my machine
your pc should be able to run any of the ubuntu's as corfy said.
However i would recomend trying a live cd before installing and remember to defrag your windows partition before doing the partitioning if you want to keep windows (this will lower the chance of errors)
Amd Phenom 2 p920 Quad Core, 4gb DDR3 Ram, ATI Mobility Radeon 5650, 500gb hdd, Ubuntu 10.04 and Windows 7.
