I just spent about $1200 on a new rig a few weeks ago, here's what I got:
Tower: Coolermaster HAF 912. It's cheap but you get a quality case that stays cool, is very sturdy, and lots of room.
Processor:Intel i5 3570k It's about as powerful a gaming CPU as you need at this point, and overclockable.Toms Hardware recommended it.
Processor Cooler: Coolermaster Hyper 212 EVO. I don't believe in water cooling, it's never been reliable enough for me. While this thing is big, it works very well.
Mobo: Asrock Z77 Extreme 4. This thing has been a dream so far. Also saw on Toms.
Memory: 8GB Crucial Ballistix Sport came w/ mobo free at Newegg
Video Card: Powercolor Radeon HD 7870 Myst Ed. Haven't found anything I can't max at 1920x1080 yet. This was also a Toms winner.
Hard Drive: Samsung 840 Pro 128GB SSD. Very fast and reliable which is what I was going for.
Power Supply: Corsair 500W CX500M Modular
Monitors: 2 ASUS VH238 LEDs w/ speakers. These things are excellent for the price.
Optical: LG DVD burner.
So far this has been a very solid rig and I'm right at about $1200.
As far as the new 4th generation Haswell Intel processors, I haven't seen any articles saying anything positive about them yet from a gaming perspective. The power is lower, they have better integrated graphics (still a joke), but not much else and they're quite expensive as they're new.
