x86 or x64?

[leonheart-dsl]

hi

how can i see what version i have?

since some x64 drivers dont work while the x86 (32bit) versions sometimes work.

i have the 5342 ultimate edition ( i thought the ultimate was 64bit-only??)

any help please

also i would like to know whether there are drivers available for the 7900gt since i have no good drivers for my videocard.
