hp G 62 A10se or Dell n5010

in my local market both of them have the same specs, same hdd(320GB), 3GB Ram, i3 processor

but the only difference is in the chipset.

HP uses the hm55 chipset..
while dell uses the hm57 chipset.

what is the difference between the two and which is better?

which one should I go for?

Thank you
