(this is my current rig)
Processor:Intel Q6660
Motherboard:Intel DG33BU
Graphics Card: eVGA nvidia 8500GT 1.2 gb
Memory: 2x1 gb Transcend 800Mhz
Monitor: Acer AL1916W

and a reliable 450W PSU
I'm sorry you did that without my input. 2GB of RAM was probably plenty, for what I'm assuming was a WinXP machine because it's 32b. (Not knocking it, that's what I'm running and I have 4GB of RAM).
As others said XP 32b will only recognize 3.5GB of it, so the 4 isn't worth it, but I plan to upgrade to Vista/Windows7, which is 64b.
If I had the opportunity to answer your question I would have asked about your Harddisk situation. Many people overlook this and it's where your computer can load and open programs a lot faster. If you haven't already done so, buy another HD and set it up in Raid0. You will notice a big difference. If you could get two 10,000 RPM HDs in Raid0, you'll be satisfied. Otherwise save your money and wait for SSDs to drop in price.
That being said. You will probably need to upgrade your Power Supply in the near future, depending on your case fans and how many input devices you have hooked up. For right now 350-400W should suit you plenty, as long as it has enough amerage along the different rails (3/5/12 V). Though, having a good 600W is probably good to play it safe.
Goodluck to you.
