HP Firebird 803 VS. Dell XPS 730 H2C?

Okay, well I've narrowed my search to these 2 Units for a Gaming Rig. I play Crysis,Sims,Halo's, I also want to have it ready for Crysis 2 which is coming out next year I play A lot of War Games COD's, Racing Games, Flight Simulator Games, Some Video Editing, A lot of Music, and a big library of TV Shows, Movies, and just pictures. So Which one would be better Price isn't the issue and I can get the Dell XPS unit that I want at a good Price at about 2,500. Which is the Liquid Cooling, Over Clocked Processor, Dual Graphic Cards. So it just comes down to Value. I am Building my own PC but I'm waiting for some parts that will be coming out later this year. So I need a unit Now. Price isn't the issue as long as its under 4,200.00 What are the Pros and Cons of each unit. Also which games can I play on the Highest Settings and which games will choke/lag and at what settings can I put those games on to make it smooth. The Best Answer gets 10 Points.

HP Firebird - Specs

The Price of the Firebird starts at 1,000.00 and ends at 2,000. The Dell starts at 1,600 and the Configure I would get is about 4,000

If I get the HP Firebird I can get a new Playstation 3 (Mine Broke) or if a New PS3 Slim comes out, Purchase a 25" Monitor up to 1080p Resolution, and if Apple Releases a Touch Screen Netbook/Tablet. Also some games for my consoles and PC. Which is why its so hard. Since the HP Firebird is cheaper. I can get so much more with the HP but is it worth the sacrifice in power. I have the 3 gaming consoles so Gaming on the PC would be nice but not 100%.
