Windows 7: upgrade 32bit or 64 bit?

Hi, i bought a used Dell inspiron 1501 with XP pro and thinking about goin to win 7. I got no disc's with it .My question is after goin to win 7 will i have a problem when it comes time to REINSTALL win 7 at a later date (2-3 years) from the UPGRADE dvd as there will be no previous OS on it.

Also it has the 64 bit AMD 64 dual core running @ 1.8ghz i believe with 2 gig ram which is shared w video.will it run the 64 bit version well??? MAX ram is 2 GIG should I install 32 bit or 64 bit???

THANKS in advance Robert...

It will, but with the memory you have, you wont notice any difference from the 32 bit version... MS recommends a minimum of 4gb of memory for 64bit...

Clean Install Windows 7

Here is a link to our tutorial regarding a clean install, with an upgrade DVD, when there is no OS installed. I think that after you read this you will see how it easy it will be to install a few years from now.

Would someone address the second part of my post
AMD 64 1.8ghz dual core with 2gig ram (MAX).... 32 bit or 64 bit upgrade???

THANKS Robert

It actually was answered by Tews. I did not answer but I agree with Tews. 2gb or less stay with 32. Others will come on and disagree. I do not think that it will be worth your while to go with 64. Although limited, there are problems with 64, with appl etc. I just had one poster who could not get her printer to work with 64.

Thanks,I need to check my reading glasses Will do the 32 bit upgrade..
