Should I buy a 2010 MacBook in 2014?

I found a used MacBook Pro 15-inch from 2010 with these specs:

Intel Core i5 2.4 GHz
8 GB RAM
Intel HD 3000 graphics
nVidia GT 330M
320 GB HDD
OS X 10.9.2 Mavericks

Those are quite good specs and it's only or $830.

My other choice is a 13-inch MacBook Pro from 2012:

Intel Core i5 2.4 GHz
4 GB RAM
Intel HD 4000 graphics
500 GB HDD

For or $850.

I'll be using the computer for web surfing, movies, music and all that. I would also like to play Minecraft on it. I like the bigger screen of the 15-inch, but I think it might way too outdated, even though Apple still sells i5 MacBooks.

Please, help me decide. Note that I'm not buying a PC, it has to be a Mac.

Considering you can buy a used 13 or 14inch pc laptop with an i5 2.5ghz for $200, a macbook seems like not such great deal at $600 to $800. But its your money.

Yeah, as long as it still functions just fine, the second one in particular is a great deal.
