Urgent: Need Advice on new SSD

Hey everyone,

I am going to purchase a second SSD and have it just for games.

I currently have 1 SSD that my OS (Windows 7 64bit) is loaded on as well as a few games but I have reached my storage limit and with the release of a couple new expansions to the games I currently play on the horizon I need to purchase a second one. (I also already have a 1tb Samsung F3 Spinpoint for storage of files and videos etc).
TRIM is not currently supported if I RAID 2 SSDs together, for this reason I am going to keep them as separate partitions in my computer.

My issue is this:

I could ethier get an Intel x25m 80gb SSD, which is clearly a better drive than my current SSD

or

I could get an identical SSD to the one I have now (Kingston V+ Series 64gb), for the sole reason that I believe it is possible in the future that they will allow TRIM command to pass through the raid controller, making RAID 0 superior, and a possible option that I would have the hardware for

The Intel x25m is only $10 more than the Kingston, which in my opinion is miniscule and holds no weight in the decision.

I am also expericeing issues with my current SSD (Kingston 64gb) and after going through countless reviews and looking at Intel's support pages for available utilities it is clear that the Intel SSD is superior, I would much rather get the Intel SSD but since I already have the Kingston one I'm wondering the chances that trim will ever pass through raid controllers and would I really be missing out on a lot if I loose the ability to ever RAID0 my SSDs? because I know I will be reluctant to buy a third ssd short of a current one dying or me winning the lottery.

I need to make a decision by Tuesday night, Wednesday at the latest.

Thanks in advance for your imput!
