Sorry, I was gonna leave links to specs of each, but was pressed for time and wanted this out quickly.
What is the maximum amount of money you can spend on buying your parts? If you tell I can select the parts for you.
CPU: You don't need a i7 for gaming and get a haswell cpu like the i5 4670k.
CPU Cooler: A liquid cooled one is the best
Motherboard: Depends on budget and preference.
Memory: Cheapest you can find at 8Gb max and either 1600mhz or 1866mhz.
Storage: A small ssd for the os and a large hdd for normal storage.
GPU: Depends on your budget.
PSU: 750w if your going to sli later on or 600w if your not.
Case: Depends on preferences, but probably a ATX mid tower.
OS: Operating system costs money as well.
