Which laptop to buy

Hi i'm looking to buy a new laptop, mostly for gaming and found 2 laptops which i can't decide between

This laptop would be alot more portable and has a better gpu

While this laptop has a better cpu, it's cheaper, it's a lot more easy to collect and i trust the retailer more

i know the Acer would be better gaming wise because of the 640m but i don't think i would be doing much gaming would fall out of the reach of the 630m mostly just skyrim/fallout on medium settings.


Thanks
