Will it matter on an dell m90 running xp since xp only recognizes 3gb anyway? I play cs source and some fps games, and do a lot of multitasking.

Considering the price of memory I vote 4 GB, you get Dual channel which is a little faster, and you will have around 3.25 GB available.

Playing CSS, you probably will not need more than 2 GB on XP. However, as Dave said, memory is cheap enough so that you could upgrade anyway. Maybe you should just do all your most intensive apps one day and then use task manager (performance tab) to check your peak commit charge. The peak commit charge is the maximum memory at any given time ever requested to the OS (however it resets on reboots).

What should the peak commit charge be around? Or a better question is how will I know more ram is needed?

mushkin 4GB (2 x 2GB) 204-Pin DDR3 SO-DIMM DDR3 1066 (PC3 8500) Dual Channel Kit Laptop Memory

I'm not sure about the compatibility of it.

No, you need 200-pin DDR2 modules.

And your peak commit charge should be less than the total physical memory.

Well depending on the timings of these RAM modules, one will be faster than another although the difference will be negligible. Note that since DDR2 is both forward and backwards compatible, you can put the 800 MHz stick in your 667 MHz FSB machine but the sticks will only operate at 667 MHz (with better timings than advertised on the chip)
