not worth the expense of upgrading your win7 ot 64bit unless you are doing something that requires it. Nothing you said in this or your other post indicates the upgrade is needed.
This may seem a bit strange, but I think it's well worth asking. I have a 64-bit machine that was (I guess) built with 32-bit OSes in mind, so it is hardware limited to 4GB.
If I load Win7/32 I don't get all 4GB, but the machine will function adequately. Is it worth loading the Win7/64 to gain access to that little extra piece of memory or does the extra overhead make this unjustified?
