I don't know if I am being a little dense here, but I'm going to be building a HTPC in the next two weeks and was going to put 4gb of ram in it. I know 32bit OS cant actually use 4gb, but is it worth actually spending the money on vista 64bit? (I have a 32 bit licence copy already).
Also if I do go 64bit will all normal software work on it or do I need specific 64bit software. Are there any advantages to 64bit?
Cheers!
