Hello Bray 570,
The builds posted by some of the other users are fine, but there are some things I would change for your given budget of $1500. That's a lot of money to work with, and getting a B75 chipset motherboard is really limiting. Instead of buying an i7-3770k, I would recommend getting the i5-3570k because for your uses, it should be quite enough for much cheaper than the i7. A Cooler Master Hyper 212 Plus/Evo will be suitable. I recommend the Plus as the Evo is virtually identical for $10 more. For RAM, I would get G.Skill or Corsair 8gb at 1600mhz, and upgrade down the road if you're not satisfied with only 8gb. In my experience, 8gb of memory has proven to be more than enough. A Samsung 840 Pro SSD is my recommendation for a boot drive and to store games. A Western Digital Blue or Black 1tb 7200 HDD is sufficient, or a Seagate with the same specifications. For a video card, I would recommend a Radeon HD 7970. It is quite a step up from the 670, and you can afford it by getting the i5 instead of i7. Personally, I would get a Corsair TX650 or CX600 over any Cooler Master PSU. Besides that, everythign else looks good. Let me know if you hvae any questions.
