There are still a lot of options out there for a system within the $1,000 budget range. Trust me, we just built 4 design systems for $1,200 each and they blow away anything comparable from Dell or likewise, you just have to plan which is why you have come here to get information.
I still would highly HIGHLY recommend waiting until the new chipsets from Intel are released as it will offer even more options and will reduce the price of other platforms in the market as well. This can already be seen by last week's price drop of several of the 1366 socket processors by as much as 48%. A Core i7 2600K may be a little out of the price range for a $1,000 budget system, yes, but the Core i5 2500 might still be feasible in this budget once motherboards are released and I guarantee it will outperform other options in the price range.
If you need to order a system today, this is the kind of configuration I would suggest, it is very similar to what we went with at our offices to upgrade just recently and has been a stellar configuration.

These are some very competent systems with plenty of performance for design needs. A couple things here to point out that are important. Unless you are doing a lot of 3D design such as CAD work, you don't need a powerful graphics card at all. In fact, today's integrated graphics are more powerful than a lot of dedicated graphics cards from a few years back. The most I would recommend on spending for a graphics card would be about $100. The GTS 450 in this configuration is just slightly above that, but I have had good luck with the PNY brand and the 450 is more than enough power for years of design usage. It is the best price-performance ratio for this kind of design work, as if you are spending any more to get a more powerful card, you're only getting gaming performance which in daily design usage you are going to see no benefit compared to the 450 but will have spent a ton more money on it. Next, the Western Digital hard drive I selected is a very fast and high quality hard drive. It has a massive amount of cache memory which can increase the performance of the hard drive, plus it comes with one of the best warranties that I have ever seen on a hard drive, 5 years. I've used this hard drive in a TON of systems lately and have been thoroughly pleased by its performance. When comparing the Intel and AMD system I configured above within the $1,000 budget, I'd tend to lean towards the AMD system as you are getting more cores and faster clock speeds all for about the same price. Benchmark comparisons of the two platforms would say that the Intel platform performs slightly more efficiently clock-for-clock, but when you take into consideration the higher clock speeds and 50% more cores, your modern design software (like Adobe Photoshop and the rest) will have a greater advantage with the combination of more cores and higher clock speed.
That being said, latest testing with the new generation of Intel processors (which have had motherboard recalls due to a transistor design flaw) places the Core i5-2500 (which would be within your $1,000 budget for a system) at out-performing these processors without much problem. Add to that the new chipset advantages (a faster SATA6 interface than the same SATA6 interface on the 890FX chispet from AMD, double the bandwidth throughput on PCI-e connections for faster graphics, network, and hard drive interface speeds, higher efficiency, and support for up to 32GB of DDR3 RAM compared to 16GB with the options above) I'd still have to recommend waiting to see how the cards land in a month when the motherboards are released again by the manufacturers with the fixed chipsets.
