Updating my CPU

Hello everyone!!! I currently have a AMD A8 5600k running as a cpu, and I am planning on changing it! I have around 300 euros to spend, so I would i love some advice from all of you!!!

So far, I have reached the conclusion that if i want a better cpu, im gonna need to change my motherboard, so if you could advise me on that as well i would apreciate!!!

I intend on playing a lot of games on my pc.

With the exchange rate right now, that's about 430 Euros.

Here's a 290 Euro option. It doesn't have the same amount of per core performance as that i5 option, but it's better than your current setup. http://de.pcpartpicker.com/p/BbsfnQ
