upgrade to 64 vs 32 win 7

  markcomp 07:25 08 Nov 2010

I have an acer pc 3 yrs old with a 2 ghz athlon 64 and 8 gb of ram running xp 32.
The MS win 7 advisor suggests an upgrade to 32 bit win 7 vs 64.
I have read all the posts about driver issues and backing up all my docs etc, which i will do using paragon drive copy so i can keep programmes that I do not have discs for.
The reason for going for 64 bit amongst others is that although not a gamer i use some memory hungry programmes and would like to use all the ram.
Have I got this right or will an attempt at a 64 bit upgrade be doomed to failure???

Go to the Acer click here and check that there are 64 bit drivers available for your machine.

you cannot do a normal upgrode from XP TO win7 you need to do a custom (full install . download the tutorial from click here it takes you through the entire process ,follw the steps and you wont go far wrong .
good luck .

32 bit Windows will only utilise 3.25GB of ram. To make full use of 8GB you must switch to 64 bit.

I agree with Mr Mistoffelees and bremner
If possible go for 64 bit
A 64 bit PC will run 32 bit programmes, but the main point is that you will "waste" half your RAM with a 32 bit PC.

Hi markcomp et al, this has been a useful thread for me. I have a 2yo Acer 8930G with 4Gb of RAM. It came with Vista 32-bit. So can I install 64-bit Windows 7? The Acer site in bremner's link seems to suggests 64-bit is ok for this machine, what other things should I take into consideration? One thing I can already think of is the monitor driver; I tried the Windows 7 upgrade (32-bit) and first thing I discovered was the screen resolution would only go to 1280x800 (on my Vista system it was 1920x1080).

Thanks to everyone for their comments and feedback - am going to attempt a win 7 64 bit install once we have another machine ( the kids are getting a new one) just in case it goes pear shaped and we are without a work pc. I'll leave the thread open and let you all know
