Is a RAM upgrade possible on my Macbook Pro?

Hello all. I have a Macbook Pro that's a couple years old now. I'd like to make it run a little faster, but I'm unsure of which route (if any) will yield results. I'm considering a RAM upgrade and/or an OS upgrade. My goals are to speed up my computer for general use (internet surfing, video watching, etc), not for gaming purposes.

I have a Macbook Pro 2.2Ghz Core 2 Duo/2GB/128MB VRAM/120GB 5400 rpm (that's the label underneath the battery).

I'm running OS X 10.5.8.

Thanks in advance for any advice!!

Thank you. That's exactly what I needed.

Regarding the second question about whether an OS upgrade would also help (I guess from Leopard to Snow Leopard), are there any opinions about that? Thanks again.

Personally I would say with that machine don't upgrade the OS. Upgrades seem to cause it to go slower.

However, if you are up for a complete wipe and reinstall of Snow Leopard, that will help a little.

I would say with that machine, you should stay away from Lion, I had one generation newer, and i just ran slower with lion. And for that machine, Mountain Lion will not run, so beyond that you should be looking at investing in a new machine.
