Which computer should I get? ?

Well It does depend on what you get with the aurora. I know that the cooling would be superb on the alienware computer because they have won many awards for that.

The main thing that I noticed was the tigerdirect computer has a 600 watt power supply. Running a 64bit quad processor, dual PCI-E video cards, 7200 rpm hd, dvd writer drive, and three humungo fans(this will get loud quick unless you keep your house like Monk. The system may run but I pray to god you do not try to add anything to that. (IE multiple USB powered devices or additional hardrives or dvd drives.)

Alienware computers come standard with 750 watt power supplies.

For me it would be a no brainer to go with the alienware computer for this mere fact.

If you have the money, go the Alienware route. The CybertronPC's specs aren't bad, though you'd probably want a LOT more disk space if you're serious about video editing.

If you go with alien ware it may be hard to find parts for it unless you want to chop off your right arm and give that to alien ware. If you go with the other one you can probably upgrade with other parts. In the long run the first choice would be better for you.

the higher the specification the better
