With a $1500 budget, it shouldn't be too hard.
- Z68 based motherboard
- i5 2500k (which will leave you nice headroom to overclock if you choose)
- 8gb of nice ram (that'll run you $50 these days.... crazy cheap)
- SSD boot drive (I'd go for a 120gb personally)
- storage drive of your choice
- DVD or BluRay drive
- Video card based on what you actually want to spend on one. I never buy high end so I'd recommend a GTX 560 personally.
