Ram - 3 GB or 4 GB?

[macPuppy]

Hi
I have a new 24" AL iMac (2.4 GHz).
I'm working with 3ds max and Autocad 2007 in Windows XP, and Photoshop and InDesign in Leopard.

I have 3 GB ram in my iMac (1x1 GB and 1x2 GB).

My question is, would an additional 2 GB block (Total 4 GB) make a noticeable difference in performance? Is i worth it to pay like 50$ for the last GB?

Start Activity Monitor. On the tabs near the bottom pick System Memory and look at the Page ins/out. Mine says 332671/162370. This means that I'm swapping a lot of memory from RAM to the HD. I've only got 1.25GB of RAM in my PowerMac G4.

3 GB is a lot, but if you're not using all of it, more RAM won't make it any faster. But, if you're swapping a lot or some, then it will make a difference.

Like "bbarnhart" said, if you're not using all of your 3GB of RAM you have now, it won't make a difference getting the last 1GB. You could always sell that 1GB stick and then it won't be that much more to upgrade it.

I don't think I need the extra ram then

Thanks for the quick replies...
