Hello, congrats or joining the upper part of gaming society by building a PC! Your build looks ok but I do have a few suggestions.
First off in my opinion it's a better idea to either go with a 280x or a 770 4gb version because some modern titles can eat through a lot of VRAM and if you have insufficient amounts of VRAM your game can lag badly. Secondly, I've used ASUS Motherboards in the past and while they are nice their service is horrible. On an upcoming build that I'm making with the new intel 2011-3 processors I'm using a MSI motherboard which I've heard nothing but good things about. Asrock has also recently gotten their stuff together and have started making quality boards and I can highly recommend them. Your ram is great and so is your processor. I would suggest the i5 4690k over the 8350 but you're probably ok going either way. It's just that the 8350 is starting to show its age and the 4690k is brand spanking new. The psu is ok but I might get a 700w one just so that you're not always pushing the psu's power limit to the max, it helps the psu last longer and it gives you more electrical headroom. Also, make sure you get a high quality case. My first mistake as a computer builder was getting a cheap $40 case and I ended up having to buy a new one because the cheap one broke very quickly and also had horrible air flow. Good luck with your build!
