32 bit os ram issue

[ashatron]

Hi all :]

current set up -
windows xp 32 bit (i have a 32 bit cpu)
4 gig ram installed (2x2gb)
512mb gpu - Geforce Go 7900 GTX

This only shows 3 gig of visible, useable ram.​

Question 1)
Is it worth upgrading to windows 7?

I ask because ive heard windows 7 32-bit can use 4 gig of ram straight out the box.
is this possible?
if i did upgrade would it show 4 gig? or 3.5 gig (my 4 gig of ram MINUS my 512mb of GPU ram)?
and if money was no object is it worth upgrading for an extra gig/half a gig of ram?

Question 2)
Also, is there anyway that you can deactivate and re-activate your GPU easily?
So that the ram from your GPU does not get deducted from your currently installed ram.

Thanks!

You guys are absolute genius's.
Thanks a lot

yep defo nothing you can do for that :/ im supprised they used a 32bit cpu in that laptop not exactly a notebook?? and correct me if im wrong, that laptop comes with either the T2700 cpu which is 32bit or the other option was the T7600 cpu which is 64bit so you dipped out on getting that model with the T2700. but intels numbering system confuses the hell out me lol so I may not be correct there but it makes sense, you got the lower spec out of the two.

Yeh i thought the same,
a
t7200 or
t7400 or
t7600
would work, making it 64bit.
but is it worth the extra money?
like £50 for a t7200 :/
