I see why you are stuck, at first I was thinking go for the second one no doubt, but then you say about mild gaming.
If only mild gaming, I would still go for the Core i7 Laptop as 1GB should be enough, but obviously we may class mild differently. Also, you get $99 cash back on this laptop if you buy it from the link you've posted.
Other than the CPU and graphics, there pretty much the same.
