I went to a dual boot with Windows32 bit and Windows 64 bit. i have 4 gigs of ram. My 64 bit is blazing fast whereas 32 is fast but still slower than 64 bit. My understanding is Vue python is not compatable with 64 bit. I open my Vue files that i want to put Skin Vue on in 32 then go back to 64 bit to lay out the scene and render.
   Photoshop 7 and Cs work well in 64 but there are lost of other apps that don't hence the dual boot solution.
