Thinking about buying an SSD

[applesauce44]

Hey, I'm thinking about buying a new SSD, but I'm sure which way to go and which brands to get.

But first:
Phenom II x4 965
Asus M4A88TD-V Evo - it DOES support SATAIII
2x4GB Ripjaws DDR3-1333
GTX 560 Ti
Corsair 750TX v2
HAF 912
Windows 7 Home Premium
Samsung Spinpoint F3 500GB and 1TB

At the moment, I'm looking at this SSD: Crucial M4 CT064M4SSD2 2.5" 64GB SATA III

I think 64GB will be enough for Windows + a couple applications and a game. Am I right?

Also, can someone explain to me what TRIM is and what it does? Also, what settings would I have to change in BIOS in order to make the SSD work to full speeds?

Should be, depending on how big the game is.

Also, can someone explain to me what TRIM is and what it does?

It's a special command the operating system can send to the SSD to tell it that a block is no longer being used; that way the disk can erase it in idle time rather than having to erase it later when you want to write to that part of the disk again.

Also, what settings would I have to change in BIOS in order to make the SSD work to full speeds?

The BIOS shouldn't need any changes other than perhaps putting the disk controller into AHCI mode? Otherwise performance is mostly down to the operating system.
