SATA II vs SATA III is it worth it?

Yeah, I came from a 16mb cache 320Gb drive, to a 32mb cache 500Gb drive. The difference there is great. I would say just go with a 64mb Cache drive SATA3. Then divide up your drive into 3 partitions, make your Cdrive, 100Gb and divide up the remainder of the hard drive, for 2 more partitions. Put windows on your C and load your games on the other 2 to save space on your operating system partition. This will keep windows free and clean and fast for a long time to come...
