Well considering a majority of games that I have bought/heard about in the last few years have bad memory leaks, at least til it gets patched a few times. (a secret ploy that hardware companies pay gaming companies). It would'nt hurt. It's all up to you though but it seems memory is getting more an more important. Also Vista may have it's problems now but will probably be tweaked optimally within a year wich requires higher resources.
