Great ssd but.... if you have enough ram on your mother board and enough video ram on you CG, you dont need at all.

I test myself and i saw a huge difference between 512/1024 MB graphic card ( sapphir 4870x 512MB versus msi gtx 285 1GB) with i7+12GB RAM than my X4 ssd hardware raid 0 ( adaptec 2405 ) versus one velociraptor 300GB
