Will it be effective installing 4GB of RAM instead of 3GB in a Windows 7 32-bit system?

Will I feel any difference?

I asked a similar question last year: superuser.com/questions/40978/… There should be no performance hit, at the very least. –  techtechmo Mar 18 '10 at 23:38

If it's not that much extra cash, go for it. You'll get SOMETHING out of that extra GB (Likely .25gb-.5gb, though it depends massively on your other components), and you can install 64bit Win7 whenever if you ever need that extra bit.

The bigger issue will be how many devices/expansion cards you have. For example if you have on board video - that will subtract from your memory total. Other addon cards or onboard audio and network will also take up small amounts of memory - which is why everyones experience and amount varies.

Depends. Your system may only address 3.5GB or so. Whether it makes a difference will depend on the apps you are running. Also on how many apps at the same time.
