Hi everyone,
I want to ask :
Q: is it mandatory to buy graphics card if I buy core i3 or core i5 or core i7 processor, here I want to ask will the display come on monitor or not, that is, can I watch movies, read ebooks & do other task.
Q: Does core i3, i5, i7 ,has inbuilt graphics in it.

if you buy a retail version that is not the highest end K version, the CPU will ship with the cooler it needs.
the K series chips are for overclocking and other heroics and rely on you to provide cooling
