upgrading, will I see any changes?

[narshade]

Hi guys. My current PC specs are:

AMD Phenom II X2 555 black edition (3,2 ghz dual core)
nvidia geforce 9500GT ( 1gb gddr2)
2GB ram ddr2 800

I'm thinking about changing my motherboard to one which supports ddr3 ram and usb 3.0
So Im thinking about upgrading the ram to 4gb ddr3 1333.

So i'm wondering, am I gonna see any noticeable improvement on dolphin?´

It might sound like a silly question for most of you
but I'm not really sure the rol the ram plays in the emulation process
