Hi guys, this is my first post, and I am very happy to have discovered this site.

I am a former Mac user as of recently, as I found it (2.1 Ghz intel core2 duo) far too slow for my work needs. I have looked at the new iMacs just released, and also considered a pre built unit like the new Alienware Aurora or a Studio XPS 9000. Mainly that I liked the look of the units, but found the interior parts a bit pricey for what you get.
I have been out of the PC world for so long that I am a bit out of the loop when it comes to recommended components to install in my own build. So for some help, I'll get into what I need and what I need it for, and hope some good Samaritan will be able to point me in the right direction.
I have a budget of $2000 at the very most... I'll be happy to spend less! But I need it all, Monitor, Computer, Keyboard, webcam w mic preferably so my wife can chat with my son and I when she is away on business. Speakers, and a wireless n card.
I do some gaming... but mainly I need a computer that will not chug when I do my Flash animation work from home. The intel iMac was awful for that, and hence it was sold.
Anyhow, I hope this is enough to go on. Look forward to any reply...
