Should I buy a 7200 RPM 1TB with 32 MB cache or a 5900 RPM 2 TB with 64 MB cache? I'm going to be using this drive for gaming just for a side note. Here are the links for both: http://www.newegg.com/Product/Product.aspx?Item=N82E16822148697 and http://www.newegg.com/Product/Product.aspx?Item=N82E16822148681
