Should I install Windows 7 in 32bit or 64bit?

If your system has 3 GB or less memory, then it really doesn't matter if you are running 64-bit OS/software. They would perform the same as 32-bit OS/software.

You will only get improved performance running 64-bit software if you have 4GB or more memory. Then it would be advisable to go 64-bit with both OS and applications.

Well, most 32 bit software works..only that 1 lol, even the developer also mention it's not working for 64 bit os. Unlocker, not an old software..been around quite long..

So the whole hoo haa of moving into 64bit is just because of the RAM limitation?

if its the same unlocker i found on google, yeah it does make sense it wont work on 64-bit. it is an "extension" for explorer 32-bit. but our explorer is 64-bit (64-bit OS).

same goes to drivers. 64-bit OS needs 64-bit drivers. cant run 32-bit drivers. i think even antivirus & firewalls are affected.

Oh, Unlocker - the app that's used to unlock files that remained locked. Very useful app. Too bad it's not supported by 64-bit Vista.

Mainly. It's a big deal though, because without moving to 64-bit, you are restricted to just 4GB of memory... and that includes graphics memory, boot ROMs, etc.

It is a good enough reason to upgrade. I can't see myself using less than 4GB now.

[PsYkHoTiK]

Yeah. I did it mainly to fully utilize all my ram too. I mean I'd like it if all 4GBs of ram is used instead of only ~3GB of my 4GB (physicaly) ram used...

Let's me run more stuff that can eat it up.

I'm with Chai... I really don't see myself using less than 4GB either.

I just installed Windows 7, and I'm like WOW, so many changes, even geek like me suddenly felt so noob in PC, lawl

I don't know if its placebo effect or not, but I have this feeling that it's faster XD

The laptop im installing 7 on is only having 3GB, haha, but nevertheless, this PC would only be used for surfing the web, etc, so 64bit would be just fine.

Edit - URGH, this is ridiculous, I used IE8, 64bit version but Flash do not have 64bit version yet LAWL
