I agree with the above reply. Doing Intel is pretty costly (for comparison, you could get an i3 CPU for more money than it would cost to get an FX-8350 AMD CPU.
If you absolutely want to go Intel, an i5 CPU is the most ideal chip for the money you want to spend. An SSD should be used ONLY for Windows and non-gaming programs. 500GB is a lot to ask for, and SSD's aren't built for redundancy (in other words, moving lots of files to and from it). To cut your budget down, I would recommend going no higher than a 240GB SSD, and using the money to get maybe a secondary HDD for critical data (500GB or more). As for the video card, going for a GTX 970 means you're set for the next 3-5 years, easy; 4GB of video memory, a high performing chipset on the video card...if you can afford it, go for an ASUS Strix GTX 970. The quality is very good and their warranty handling is among the betters I've seen (which is very few).
As for the OS, if you want to get a solid OS, then TRY, TRY, TRY to find a copy of Windows 7 Home Premium 64-Bit. It's got at least another 5 years of life on it (try Amazon, eBay (recommended if you can get an OEM DVD and a product key that is legible and able to activate the OS, then tape on the outside of it), or Newegg). Windows 8.1 is still a solid OS, and you can install something like Classic Start to add in the old style start menu...but if you must get Windows 10, then be prepared for any potential bugs and issues.
For power supply, 600W will work just fine. Long as you have enough connections for the motherboard, your DVD drive, your HDD/SSD's and the video card, you'll be fine.
Beyond that, 8GB RAM is plenty for the OS and for gaming. I can't recommend much more at this point, but if you can get the CPU, video card, the SSD knocked out...everything else should come easy.
