This is my current PC.

A couple things aren't correct. I actually have a Fractal Design Define R3 Silver Arrow, but they don't offer that case on pcpartpicker. It was around $100. The ram probably had a CAS latency of 11, rather than the 9 that I picked there, and the power supply was cheaper because it was Gold rated, rather than Platinum rated, but still a Corsair AX 860.
Overall, pretty modest computer. All games run at 1080/60. When the newer games with crappy optimization start coming out, I'll probably get another 290 vapor-x and crossfire, considering the new 380 will be out, the price should drop down even more.
As far as $2400 for a laptop putting people off, that's a pure enthusiast-grade price. If you want a cheaper gaming laptop, you can get the ASUS ROG G7551 at Newegg right now for $1500. $1750 for one with a 256GB SSD. Add a $100 2-year warranty on that and you're at either $1600 or $1850. Either way, for an enthusiast-grade laptop laptop that will run you 1080p 60fps at ultra for 4-6 years, that's a really good price.
