In fact, after running one install, and deciding to go with the other, there was at most maybe a 1mb difference. Its not much. (with that setup, right after boot would weigh in 99mb ram used :)) As long as you keep the base system lean, 1gb is tons of free memory to play with. Hell, I have Gnome/Compiz and a ton of firefox tabs running, and only 1gb ram installed, and 380mb ram still free (cached... but free) Also, I think the benefit of being able to run x86_64 guests would outweigh any penalty you'd be paying in larger address space.
