It has to be ordered all from this website since i and my friend ordered here before and we both got coupons so we can save 30 euros.
Please the build cant exceed 360 euros and we are looking to get the best performance for this price, because games like minecraft and garry's mod are going to be played on a 1920 by 1080 monitor.
The APU is what I'm looking at on your list. I haven't had any hands on with one of these things but I'll drop a link to a review and some benchmarks. In the the review it says you'll definately want to invest in the fastest ram possible. The integrated gpu really takes advantage of that. Something of interest that they said in the review is that the APU can be combined with a 6series cards for dual graphics so you may want to look into that as an option for the future. Also, I read on Newegg that the stock cooler for this APU is pretty mediocre. I'm sure you can find some tweaks online to get the most out of the APU. I will tell you that I would opt for a dedicated graphics card but I understand you're working with a budget. Don't rush your build, one thing I've learned is to do plenty of research before investing your money on a build.
These bencmarks are at 1280x720 so keep that in mind.
Ill look into getting some 2133Mhz ram, i'll also be looking toward putting a 6 series card in Crossfire later on, the 6870's are dirt cheap right now. But if i want to do that i might need a bit bigger PSU, i'm changing this one to the a 500 watt version just to be safe and have a bit more headroom, thanks for the advice!
Just to give you a heads up, with the motherboard that you listed it will only take 1866mhz ram. To achieve a faster speed you would have to overclock. Of course I'm going off of the specifications on the website you listed. You should look for a review or anyone who has had this board to know whether or not it'll take 2133mhz ram right out of the box.
