I'm considering these two laptops, which one is better in your opinion:
hp envy 15 - k209ne (i5 5200U, 2cores, 3MB cash, 8gb RAM, GTX 850 4GB)
hp envy 15 - k008ne (i7 4510U, 2cores, 4MB cash, 8gb RAM, GTX 850 4GB)
The i7 is slightly better. You will notice 1-5 FPS difference in gaming and some difference in editing but overall the difference between that i5 and that i7 is very small performance wise.
If the difference in price is not huge, I would go i7 - little more horsepower.
