Welcome to Windows 7 Forums. Our forum is dedicated to helping you find solutions with any problems, errors or issues you are experiencing with Windows 7. The Windows 7 forum also covers news and updates and has an extensive Windows 7 tutorial section that covers a wide range of tips and tricks.
Personally, I wouldn't suggest doing a RAID0 as this setup splits the data between the 2 discs and if either disc fails, you lose all of the data.
If budget allows, your biggest bang for the buck would be an SSD drive. Use this as your OS drive and load games to it, put everything else on a standard mechanical hard drive. Not only so SSD's provide more speed than a RAID0 stripe with 2 drives, but it's almost instantaenous access. Not to mention, no noise and vibrations within the case.

Without a doubt, the Intel X25-M Gen 2 is one of the fastest out there for running your OS. While others drives post much faster sequential write speeds, the Intel usually wins hand down in random I/O writes...which is what your machine does far more than anything else.
If I didn't have the Intel drive, I would probably do Patriot (for 10 year warranty) and then OCZ.

You mention gaming. SSD would be the better choice, although make sure to get a good video card so that doesn't become your gaming bottleneck. And I would second Pparks opinions on the types. I have read some good reviews of the latest OCZs if you are worried about the high cost.
What is the speed difference between SSD and Raptor?
A raptor is a 10,000 RPM version of a standard hard drive. They will provide a speed boost, no doubt over a 7,200 RPM hard drive. There is very good reason that these drives were the choice of gamers before SSD's were available. These drives can provide transfer rates of about 120MB/s during reads depending upon where on the drive the data is at. Usually the access times for these drives is around the 7-8ms mark....so this is how long it takes to find the chunk of data you are looking for.
Pros: cheaper and larger capacity
Cons: louder, more virbration in the case
SSD's are flash memory based devices. There are no moving parts and no spinning platters. These drives can provide transfer ranges of 200-275MB/s during reads across the entire disk. Their access times are in the .1 to .3ms range...so signficantly faster. So, this more instantaneous access time coupled with faster read rates provides the performance.
Pros: very low power, extremely fast access time, no need to defrag, no moving parts, very fast performance
Cons: cost, low disk space, a limited number of writes. (drives may only work for around 7-10 years)
Here is a slightly more realistic view of the difference you would see between a Raptor and an SSD
