I find the 64 bit version to be on par with the 32 bit version. I do think 64 bit is faster when using it for GIS with large datasets. I have been using 64 bit for years without remorse. Now, no 64 bit Windows OS has ever been worth using.

Well, in my ThinkPad R61 (Core2 Duo CPU T9300 @ 2.50GHz) I got 1.1 times difference (in favour of 64-bit) with couple of videofiles encoded. (By the way, it means that VM performs almost 1.5 worse then the real HW). Thanks, Sergey
