Solved Upgrading Hard Drive and RAM stay x86 or go x64?

I am upgrading my MacBook 5,1; 2.4GHZ next week.
I am upgrading the RAM from 2GB to 4GB.
I am upgrading the HD from 250GB to 500GB.

I will be reinstalling Mac OS X; no problems there.
I will also have a 100GB or so Vista Bootcamp Partition; I currently have a copy of both Vista Pro x86 and Vista Pro x64 in my possession ready to use. Should I install a32bit or a 64bit edition?

I will be using it mainly for gaming (not particularly high end gaming but all 32bit games, no 16bit games) but I am unsure whether my 4GB of RAM will be fully utilised by the 32bit edition.
On the other hand 64bit isn't officially supported on this model but according to others seams to run without problems.

Should i go for 64bit or stay 32bit? Opinions and personal experience welcomed.

Welcome,

I think this article fairly represents my opinion,

as well as many others who have posted at this forum.

Bottom line, I would go with 32 bit. You will not see much of an imporvement with 4GB RAM. The suggestion in this Forum is over 4GB go with 64. MS says that you can go 64 with 2GB, but not a recommendaion of this Forum.

TY for the rep. I truly hope that my post fully answered your question
