Computer RAM/Proc Upgrade, is it useful? if so, what would you do?

[Los from Terokkar]

I have the following computer:
-Intel Core Duo CPU E7400 2.80 GHZ.
-Dell Studio 540
-4 gigs of RAM DDR2
-Nvidia GTX 460 - 1 gig
-1TB HDD
-Windows 7 64 bit

With Skyrim coming up, I checked the system requirements and everything´s good except for the Processor and RAM.

The RAM is easy, and here comes the first question, I have a total of 4 slots on my computer, and I found 2 sticks of 4 DDR3 gigs, 1333MHZ at the local store. If I remove 2 slots and place in the 4 gigs, does that mean it´ll add up to 10 gigs? (2 slots of 1 and 2 of 4) If not, how could I do this or what would you guys do in this situation? Yes my computer supports DDR3. Bonus Question! Will I be able to run DDR2 AND DDR2 together? or only 1 type of RAM at the time?

Next Question: I can´t change my processor because my motherboard won´t let me, due to it´s model. So the to change the processor i would have to change the motherboard. Is this recomendable? I heard that it hard to do and expensive. Keep in mind that I´m not a hardcore gamer, i only play WoW and future Skyrim, so should i change my motherboard/processor?

Thanks

The motherboard you have supports DDR2 ram and it does not support DDR3 , the slots are different and you cannot put a DDR3 stick of ram in a slot that uses DDR2 ram. So if you are going to change the cpu as well then you could now have good enough reason to change the motherboard because you are changing both the ram and the cpu. It is not hard to do but for someone who has never done it you should read up on it and then you will see that it is not that hard. The hardest thing is to pay close attention to the cpu and the cpu socket so as to not bend the pins , it is probably the single most important thing to do is to make sure you don't bend the pins. A good average motherboard is probably going to cost between $100 to $150.

woops, thought it did support DDR3. Anyways, here´s backfire, is there a way of knowing wether a new motherboard will fit on my computer? I don´t want to buy one and not be able to install it correctly, thanks
