Which of these laptops should I buy? - 1

Okay guys I have a budget of 700$

Normally a friend of mine recommended these two

Lenovo Thinkpad T420 P

Lenovo G510

Now what i want is the laptop that can give me a better gaming exp (COD, Battlefield, minecraft, skyrim etc)

Any other laptops suggwstions below 700$ will be gladly accepted

If you are planning on gaming, I wouldn't recommend that you get any of those. The main reason is that they have only intel hd graphics which is not really for gaming. You need to get a laptop with a dedicated graphics card. Get the Acer Aspire V3-572G-587W 15.6-Inch Laptop as seen at the link below:

This laptop will run those games better than those two lenovo laptops you were considering as it has the NVIDIA GeForce GT 840M dedicated graphics for gaming.

Get the Recommended Specs for the games you want to play.
Then just select the machine that meets the best (or better) of them. EXAMPLES:
