RF doesn't require a supercomputer. I can run RF8 on a 1st gen i5 dell laptop with onboard video at reduced graphics quality. My lenovo 4th gen i7 runs it quite well at "high" but can't quite hack "highest." But I'd recommend staying away from AMD video. Their current drivers don't support DX9. I don't know what those HP's use. I've used HP laptops, but not for RF. They're usually pretty good.
