Motherboard bottleneck me?

Solution
I've never really heard of a motherboard causing a bottleneck, but with that chipset there may be a few things not included. Not much, though, so you should be OK. Check that it has at least 8 PCIe lanes to the graphics slot you want to install the card in.

Z-series motherboards are only appropriate for unlocked K-series Intel processors.

 
The only downside to that motherboard is that it runs off of PCIe 2.0 instead of 3.0 which means the bus it is based on may not be fast enough for FUTURE graphics cards. The 970 and the i5 4660 will run at full blast as if you bought a $100 motherboard. I highly back up your budget friendly choice.
 


They are still better, support more functions, and he can upgrade to a 4670/90k and overclock if he ever wants to.

 
I never builded a pc before and have a 800 euro budget im now at 770 euro, should I keep it like this because Im not overclocking ever and if im going to upgrade again in 5-6 years ill go for a new pc :)
 


This will be a good first build. Go for it and good luck!
