Win 7 32 bit vs 64 bit

I'm looking for a new office computer, I'm looking at the Acer Veritron M421G, it comes with an Athlon II x4, 3gigs of ram and Win 7 Professional 32 bit./XP Pro downgrade.

I need the Win 7 Pro for network connectivity, but would rather see 64 bit version.

I have Win 7 Home premium 64 bit on my Sony laptop and have had no problems running any of the same software that I use at the office running on the laptop. I'm most concerned that I'm getting a 32 bit OS in a brand new computer and what kind of performance degrade I will see using the 32bit version? Also I'm guessing the world is leaning to to the 64 bit OS for future software. I tend to keep my computers for a while and can't imagine that I will be switching hardware if I have a quad core processor and don't want to have to change OS. I use MS office 2007, Firefox mostly. I multi task with 10-20 windows open multiple program in background and dual monitors. Stability in most important.

Any thoughts on performance differences with 32 bit vs. 64 bit?

Go 64 bit so you can upgrade the RAM later, and don't have to reinstall the OS from scratch (remember that there is no direct upgrade path from 32 to 64 bit - the data must be backed up, and the drive has to be wiped out). There's no reason to go 32 bit anymore, unless you're using a CPU which does not support 64 bit host operating systems.

yes 64bit would be the way to go now especially if you are going to get more than 3.5gb of ram.

I was surprised that the computer has a quad core athlon processor but no 64 bit. And as I started to look at the configuration the 3 gigs of ram made me to start to wonder if the Win 7 Pro was 32 or 64...Acers website shows 32 bit.

The CPU itself is 64 bit capable, it's just that OEM's (for some strange reason) seem to keep bundling 32 bit Windows with their new computers. It drives me crazy TBH... there's no need to continue doing it.

i've had dell telling me that you can only choose 64bit if you get 6Gb of Ram, so what you are meant to do between 3Gb and 6Gb i don't know.

OP go 64!

Or you have some strange need to run old 16-bit applications without emulating the CPU.

Good point, however one can get around that if they are using Windows 7 Professional or higher by downloading the Windows XP Mode virtual machine.

you can put 4 or more gigs of ram in your system but you prolly wont register or use more than 3.5g of it unless you have a 64 bit operating system. also most 32 bit programs will run faster if they're run on a 64 bit system versus a 32 running a 32.

internet explorer 64 can only be run by a 64 bit processor however it sucks because there is no flash player for 64 bit IE

IE also doesn't need access to more than 4GB of ram by itself, so running it is basically pointless, regardless of Flash support.

One popular application comes to mind, unfortunately, as a reason to use 32-bit: East-Tec Eraser 2010. Most eraser programs do not even address the elimination of Windows shadow copies. Eraser 2010 does, but only for Win7 32-bit. It has no ability to erase shadow copies in Win 7 64-bit. I have had several emails with East-Tec about this and they have no plan at this time to add shadow copy erasing to 64-bit. It may be that they are unable to.
