Lenovo y510p Processor and GPU Questions

[EgoRiot]

Hey there so I'm really interesed in buying the 510p but just want to get some expert answers over some topics that have been dwelling in my head.

1. Is there a big difference between the i5 processor with GTX 755m sli and the i7 processor with GTX 755m sli? I want to get a good gaming experience but don't want to waste money

2. Can you have 3 gpus in the form of 755ms? I know there is one GPU in the ultrabay but is there another one in the other or can I just add another gpu to the already 2 present gpus?

Most people are of the opinion that The i5 is better for gaming as the processor is better used by the games. Games tend not to make best use of the i7 as it is more geared to multi tasking things like graphic rendering or music software
