Here is why I need advice. They both essentially look good to me as they seem to be almost the same machines. It looks like the Alienware has a better cooling system and power supply, but only comes with 32 bit VISTA, which means I will have to upgrade to 64 bit and also pay $100.00 for shipping. I also know Alienware makes a very good product as I have a 3 year old machine now.
The newegg machine has a 500gb hard drive, 250gb more than the Alienware. It also comes with 64bit Vista, but it only has a 650w power supply. If I get the Alienware, I can also trade in my current PC, and get some cash back, at least $200.00, which would pay for Vista + shipping. So I guess it comes down to power supply + hard drive...any ideas?
