For 2000 zed, you can get a lot of computer.
Sometimes we sacrifice performance over SSD.
The 4770k just came out, and while it isn't much better than the 3770k, it is better, and costs practically the same. Pair it with an MSI GD-65 "Gaming" Z87 motherboard, and you'll be able to overclock that 4770k nicely to 5.0gHz, if your chip can keep up. Alternatively, you could drop the case to a cheaper one, and switch out the GD-65 for a ROG Hero or MSI Mpower, and have a better overclocking board; the GD-65 holds its ground very well, though.
Speaking of overclocking, the Phanteks PH-TC14PE will be good up to a 5.0gHz OC on that 4770k; it handles 4.8gHz on my 3770k under 74 C running IntelBurnTest small FFT; fantastic cooler, much better than any CLC out there, especially for the price. Pair it with some nice fans, and the only thing that will beat it is a custom loop, or a phase changer.
16GB of G.SKILL Sniper memory; 8GB sticks, so you can max your board out later, plus, it is sure to hit 1866mHz CL9 at 1.5V, because from what I have read, they are the exact same DIMMs as the higher-clocked sticks. Great memory; well built, overclocks decently, low profile, and solid black, all for a reasonable price.
Instead of a small SSD, I went with a 2TB Seagate SV35.5 drive. The Barracuda drives have a 30% failure rate. My data is worth more than the risk - the SV35.5 series is much more reliable, and very close in cost, making them a better choice. Based on other decisions in the rig, there was not room for an SSD.
I chose not to go with an SSD for the next thing; 780 2-way SLI. Sure, triple 7970s would give more power, but the issues with power consumption, frame times, microstuttering, games that don't support SLI or CF, etc., etc. make 780 SLI a fantastic option, especially considering it is within your budget.
The R4 isn't as well-built as the 350-D, but it is made like a tank, regardless, and just looks great. Solid cable management, and plenty of drive-bays - great case, especially for the price.
This system, even when overclocked like crazy, will never need more than 750W. You could even use a 650W PSU, but for longevity of the PSU, running at 85% load is ideal, both for reduced strain on the PSU, and optimal efficiency. The Corsair AX750 is fully modular, and has a very low ripple, which will help protect your hardware from a PSU-based overclocking explosion.
