Ideapad Y510p i5 or i7 for gaming?

I'm purchasing a new Ideapad y510p especially for gaming but i'm confused between i5 and i7 so please suggest me which one better. Or does i5 works fine with 755M SLI card?

Its a good choices for gaming i5 is really good for gaming if your budget permits you go for it otherwise is not really a big deal. I think there are no SLI cards available in India how could you do so?

Best to go with a i7 quad processor the i5 is kind of sluggish when it comes to running good specs on laptops, i5 quads are great for desktops also that lenovo laptop has a ultra bay for upgrading the graphic card is why it's sli 755m, gaming i would suggest the i7 quad for the laptop

If your budget permits, then go with i7 processor
