Actually, I use an i7, and when running more intensive programs all logical cores get used. It also affects what you can run in the background while playing. Besides, I'm guessing he wants that PC to last 5-6 years.
I agree that he should get an i5 if he can't afford an i7, and I agree that the graphics card should be of a higher priority, but an i7 is definitely not a waste of money.
Why would you want to do that unless you're playing really old games?
You don't build yourself a high-end gaming rig for those games in the first place anyway.
Since the OS has those "Cores" it uses them.
Your game will use two (most likely) either way. There wouldn't be
any difference if you had an i5, unless you're really pushing the CPU to its limits in the background while playing.
Again, why would you do that?
And don't say "Because I can", since the price difference between i5s and i7s is quite high, for no performance difference in applications that don't utilize the extra potential of the i7s. Don't forget that this is a thread for a gaming-rig; exactly this kind of applications.
And no, to make this perfectly clear, the i7s
are not bad. They just aren't worth the money when it comes to gaming, since you don't utilize the extra potential at all, while there are components that you could have spend the money on that would make a difference.
If he can afford an i7, it means that he can afford to spend the money on parts that would improve his experience.
