Dell Inspiron 15R 5537 vs Lenovo Ideapad Y510P (59-389687). Which one is better in terms of gaming and why?

Lenovo Idepad better than Dell Inspiron.
You can play game more better. Lenovo has a 4700MQ (MQ CPU's the better). MQ is performance CPU.
Dell Inspiron's a 4500U CPU (U CPU's not the better). MQ's the better more than U CPU's (x3).

So, CPU's necessary.
