Need help with upgrading RAM

[socalking]

Hello! I currently am at awe right now.. I have an Asrock A785GM-LE motherboard --v Link

But, I want to upgrade to a quad core processor,
This is the one i want to get, http://www.newegg.com/Product/Product.aspx?Item=N82E16819103727

The thing that's confusing me is.. Would my motherboard support DDR3 Ram? I'm really confused right now as it seems that AM3 Quad cores need DDR3 ram but I can't find anything about my motherboard accepting DDR3 , but it accepts quad core processors.

So.. How could I upgrade to quad core processor , but I'm only stuck with DDR2? or will DDR3 work on my motherboard? If so.. I would appreciate a link to a good ram stick.
Edit : I want to upgrade to 8gb of ram so.. 4gb per stick

Your motherboard does not support DDR3 ram. DDR1, 2, and 3 all have different pins and pin arrangements. It only supports DDR2 ram.

As for the new CPU, it looks like you can upgrade that without problems. What kind of CPU do you have now?

And as far as I know, 4gb/per stick DDR2 RAM only exists with servers. The highest amount of ram you can get for your computer is 2GB/per stick.

I currently got a Dual Core 2.8GHZ 5400+ AMD processor.
As for my ram.. i only got 1gb sticks but..

I found some 4GB Unbuffered DDR2 ram sticks on NewEgg

^ Is that good?
I know DDR2 is expensive and willing to pay the price
