Help on laptop choosing

hi guys..my dad bought me a acer aspire 4330 which is a shipwreck form the start. so im planning to sell it and get a new one..i dont know if this is the right place for this question but im stuck on choosing between two laptops..the compaq presario cq40-107au and the compaq presario cq40-310au..i wish i had more choices but these two are the only ones that fit my budget..the two units have almost the same specs. the main differences are the processor and the hard drive capacity. the cq40-107au has a amd athlon x2 at 1.9 ghz and only has 160gig of hardisk. on the other hand the cq40-310 has a amd turion x2 at 2.10ghz and has 250gig of hardisk. help please.

here are the links to the compaq units:
