HD/SSD help for game recording/playing

[notshugo]

Hi, I am new here but every time I have a question google directs me to here so I am finally going to ask. Little scared but doesn't hurt to ask. I'll try to be as detailed as I can

First I have two hard drives already they both are
WD-120GB (WD1200JB-75CRA0)
WD-500GB (WD5000AAJS-00A8B0)

I don't know anything about them. I've googled them and I can't really compare them to anything to know where I stand.

On Windows Experience Index I get a 5.9 for HD

Now I want to buy an SSD
This is the 32gb SSD I want to start out with.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820227510

Idk what is but I hear that SATA III is better. Should I spend a bit more cash to find something that is SATAIII? or SATA II just as good? Also what is RAID and how can it help me.

To improve my game play/video (FRAPS) recording/editing for school. I hear that if I have a dedicated HD for fraps recording. I could get better recording FPS. Now I'm not sure what HD would be best to do that on. I don't know anything about transferring thing from one HD to another/ switching OS to another HD.

My computer specs are -
MOBO- Giga-Byte GA-G41M-Combo Motherboard.
Processor: Pentium Dual-Core E5500 @2.8gh
RAM: 4GB
(upgrading to 8gb waiting for it in the mail http://www.newegg.com/Product/Product.aspx?Item=N82E16820231461)
Graphic: NVIDIA GeForce GTX550 Ti
both my HD:
WD-120GB (WD1200JB-75CRA0)
WD-500GB (WD5000AAJS-00A8B0)

Thanks a bunch - notshugo

Your motherboard does not support SATA III but it may be worth extra money to get one in case you upgrade your motherboard. Also I would recommend getting at least a 60/64GB SSD. For $30 more you can get a 64GB Crucial M4 which is a great drive:

And here is some info on your hard drives:
WESTERN DIGITAL WD1200 120GB 8MB ATA-100 HD WD1200JB-75CRA0 (From around 2003) IDE DRIVE
Western Digital Caviar SE 500GB SATA WD5000AAJS-00A8B0 7200RPM (2008 or so)

I will take up that SSD, in the future i am going to upgrade my MOBO, but what would be best for FRAPS recording?

This is pretty much what I am trying to do

Record videos for league of legends and get the best FPS I can.
Edit videos w/o slow rendering
Scenarios

A. Put League of legends only on SSD and record on SSD/Edit on SSD
B. Put OS on SSD and League of legends on WD500GB and record on (not sure which one I would record on)
C. Don't put anything on SSD and record with SSD.

or what would the best scenario for me to do?
Also if I record with my SSD and transfer it to my 120-500GB HD's, that would be more efficient?
