Difference Between i-5 and i-7 Laptops

although there is not much difference in performance compared to existing processors but still both are good for normal use and 70-80% of gaming heavy softwares . please take care about the Graphic Card and RAM to get the best performance of these processors( i-7 or 3rd gen i-5) . so take care about it. like 1gb of Graphics Memory and 3gb RAM with a 400-500gb hard-disk best as compared to prices .its more than enough for gaming also. you may increase if you want .

an i5 processor have four cores while i7 have up to six depending upon the model Comparably i7 have very difference in performance I don't think that the 3rd generation processors have a great change in performance than 2nd generation So 2nd Generation i7 will produce more throughput than 3rd generation i5

Hey, man CPU production has reached quite a high level. But video cards and RAM are still needed to be improved, especially for laptops. So you may not consider too much about CPU. Focus on video card and heat release system. That's my suggestion.
