it's because it's CPU's are based off of Intels clock speeds not AMDs. Any time you see that on games, it's based on Intels. Yours is 'kind of' like a 2.8GHz Intel of a similar core and whatnot so obviously you'd pass the CPU part of that. Just like I failed on oblivions recommended because it wants a 3GHz CPU.......AMD doesn't even make a 3GHz CPU lol, so that tells you it's Intel they are basing it off of.
