I am considering a new laptop for my son for use overseas at US mil bases. He wants quadcore, at least 2.0 Ghz and prefers AMD and ACERs. I'm debating between ACER AS 5552-7474 ($399.99, 4G, 320 GB, AMD Phenon II 970 quadcore, Radeon 4250) and the HP DV6-6110 ($449.99, 4G, 640 GB, AMD A6-3400 quadcore, Radeon 6520). I've read the Phenom II doesn't have a third cache, and then that it does. I've read it runs too hot. I've read that the A6-3400 is just as fast because it has hyperspeed (or whatever it's called). I've read it's better to get the larger hard drive. He does some gaming, runs lots of programs at once, will be taking some online courses, and has a quadcore desktop. Don't know if the HP is an older, renamed Compaq (he definitely doesn't want), and don't know what to do. Please keep the answers in layman's terms (educated and intelligent, but not tech-educated) please. Thanks for the help.
