Hot Hardware: Another month, another new MSI notebook. This time, the company is introducing a new F Series of laptops, including the FX620, FR620, FX720 and FR720. All of those employ Intel's 2nd-generation Core i5 CPU, and if it's horsepower and variation you're after, these have it. The 620 models have 15.6" displays, while the 720 models have 17.3" panels.
