Should play For Honor at medium-high settings at 1080p pretty well. Will easily handle Overwatch and CSGO. Is this a system you already own though, or plan on buying?

It is a system that is not currently built.

My friend has never had a gaming pc, he has been using a crappy laptop for the past 6 years. He has been saving for parts, and has everything besides a CPU. He hasn't had the money to spend to get a cpu, so I was gonna chip in and buy him a cpu that I can afford right now. And the i5-2500 looked like a good choice.

And i listed those 3 games, because he plays Overwatch and CS a lot, and he really wants to play For Honor.

The GTX 760 and Sandy Bridge i5 are quite old, it doesn't make sense to put either of them in a new system.

These are the only components that he can afford.

He plays most games on super low settings at 20fps, with his current laptop, he just wants something that can run his games a bit better. He doesnt want anything special. This is the build he can afford atm

I very much doubt it. You could have got a more modern i3 and GPU for the same price most likely which would have performed similarly, or even better.
