Any of the setups you go with here will play you games you wanted so don't worry about picking the wrong stuff. I have always used the built in soundcard you might want to stick with it for a little bit and upgrade later.
The i5 cpu is really nice but is double the price of your starting cpu. The fx6300 for $120 might still be a good way to go. Make sure the board you buy supports the fx9590($350) and you can upgrade in a few years when its under 100.
the 760 and 260x video cards are both very good cards. If it was me I would go with the 760 its a little faster and in my view has a little more support due to a lot of people using this card.
Cases and cooling depending a lot on how hot it is where you live and if you have AC. For me. I buy the cheapest case as im live where it is cool. Almost all cases have room for extra fans. You can buy more if needed. Just make sure the cpu fan for the motherboard you buy isn't going to be in the way of anything.
(it would be rare for this to happen just kind of check by the pictures)
Power supply, Just make sure it has good reviews. The watt rating on these are kind of fake. Compare the amps on the 12volt line. What ever is bigger is better. Or just get a 450w+ with a good review
