There are problems with drivers in 64bit OSes. Most hardward manufacturers are not dedicating many resources to writing drivers for an OS that very very few people use. Also, I believe that using a 64bit version cuts your memory in half. Have you been enjoying that gig or memory? Upgrade your OS to 64bits and now you will have 512mb.
That's a lot of misinformation there.
How does it cut your memory in half?! I'd really like to know.
But to debunk the post:
(1) Driver support: Yes, it has been iffy in the past, in XP 64-bit. Nevertheless, even with XP 64-bit, all mainstream hardware was well supported. With Vista, 64-bit driver availability is part of the WHQL certification. If a manufacturer wants that certification, they must provide a 64-bit driver. It will make availability much better. Unless you have some off-beat hardware, you'll be OK.
(2) Memory: The 64-bit version uses just about as much memory as the 32-bit version. It does not cut anything. As a matter of fact, the 64-bit version removes restrictions that 32-bit has.
(2.1) 2GB per process MAX in 32-bit.
(2.2) 4GB addressable MAX in 32-bit.
A 64-bit machine/OS can address WAY over 4GB total, and can give each process WAY more than 2GB.
I anticipate there will be SOME hardware where drivers won't be available, but mostly really old or off-beat stuff. Replace that 10 year old TV tuner.
Also, the 64-bit OS will still run the 32-bit software just fine. It worked great in XP 64-bit as well, with no perceivable performance loss even in demanding games.
EDIT: With Vista, you want 2GB unless you enjoyed XP with 1GB. If you play modern games and 1GB was barely enough in XP, get 2GB for Vista.
