In my opinion No. I would leave it on the 32bit version I bought my computer and should have checked first but it had the 64bit installed and you need double updates for flash and java and probably other programs as well if you want to use the 64 Bit version of I/E and the 32Bit. 2Gb of ram I would stay with the 32Bit. Wait and see what others think before installing any of them.
