[brandonvds]

Hi i'm looking for a new gaming laptop. And i now narrowed it down to 3 laptops.
First is a msi ge20
Intel i7 4710hq
Nvidia gtx 850m 2gb ddr5
8gb ram
500gb ssd

Price €850

The other is a lenovo y510p
Intel i7 4700mq
Nvidia gt 755m sli 4gb
8gb ram
1tb hdd with 32gb ssd cache

Price €900

Lenovo y50
Intel i5 4200h
Nvidia gtx 860m
8gb ram
1tb hdd

Price €700


So wich one should i get for playing games

They're all used but these where the best i could find within my budget

I know the 860m is best gpu but with an intel i5 is it still better or worse than the other 2
