With that price range, I would recommend an AM2 processor. You should be able to get something along the Athlon 3500-3800 (@ $150)and still stay within budget. And if you want to upgrade later on, the same motehrboard will support the AM2 X2 5000, which is about the fastest one out currently. And it will support the quad-core when it comes out next year. And no matter what, do not buy an "OEM" processor. In order to save $20-30, you give up a CPU cooler, and the warranty. Retail box processors have a 3 year warranty, OEM only have 30-90 day warranties.
Stick with a better quality board, like Asus or MSI. The Asus A2M-E runs around $120, and has PCIe, multiple SATA, and about anything else you would want.
For a hard drive, avoid IDE and stick with SATA. They normally run around $10 more, but are well worth the money.
Do not go overboard on the video card. Stick with a single card in the $100-150 range for the moment. Even if you plan on going SLI-Crossfire, hold off on buying them. There is a new generation of cards comming out in the next few months. Spending $300-1,200 now will seem really foolish, when come January they are already outdated.
Do not go cheap on the power supply or case. Make sure that as a minimum, the power supply is at least 400 watts. Make sure the case is properly ventilated, having at least 1 120mm or 2 80mm fans in front of the hard drives, and the same thing in the back of the case.
And especially if this is your first time building a computer, I suggest looking local for a supplier. One big advantage of this is that you get some local tech support. The parts may cost a little more ($5-10), but if you have a problem most shops will give you some tips or assistance in fixing them.
One of the most common things I see new builders do is to assemble the motherboard, and not use the stand-offs when attaching it to the case. Or not know how to attach the case leads to the board, or not understand how to install SATA drivers. These are the type of things that we (or most other shops) will help with for no charge. Good luck calling New Egg because something does not work right.
Plus, you are dealing with somebody local, selling things that they are familiar with. When you take into account that you can just walk out the door, the costs often turn out to be the same. NE may beat us in most items, but once you add in shipping, the cost is really about the same. But you do not have to wait 3-5 days for the local store to ship the item.
