Can't really help you without a budget in the form of a number. I settled on $700 for my build when I started looking at parts. A couple points from the OT: - Ram speed is usually capped by your motherboard, as in your RAM can only act as fast as your motherboard supports. Mine will support 2400Mghz. It really wouldn't matter if I used 3200Mghz sticks. Also, the difference between 2400 and 3200 isn't very noticeable. I use one 8gb, 2133Mghz stick and everything runs just fine. Don't worry too much about RAM. RAM is RAM, as long as it's DDR4. - A 580 is a great GPU for a <$1000 build, it's not exactly close to a GTX 1080 like you said, but for 1080p/60, it'll do everything you need it to and more. I have an RX480, which was superseded by the 580, and my only complaint is how loud it can be under load. The ASUS model of the 480 I chose tends to run louder, and most user reviews reflect that. I don't worry about the temperature, a normal operating temperature for these things is as high as 84°C. -For motherboard selection, you have two form factors that are meant for most cases: ATX, and micro-ATX. I wish I had spent an extra $20 on an ATX motherboard. The issue is that everything is very tightly packed and can be hard to work with, not that I'm pulling the case open every other day, but on setup, things were very cramped. Mine also only supports one case fan in addition to the CPU cooler. A full ATX motherboard would support more, and things would probably run cooler if I decided to install another fan or two. Also, read reviews on motherboards and see what people have to say about that particular motherboard's BIOS. You'll be working with the BIOS during setup, and for a first build you want one that's easy to use, well organized, all that jazz. - Don't buy into things because they say "Gaming" on them. Especially keyboards, mice, etc. Somr peripheral manufacturers like to sell to gamers using looks rather an build quality or function.
