I am considering purchasing a Dell 9100 with the specs shown below. I primarily use this as a home office machine, but also do some multimedia encoding and burning. I play games occasionally, but not often, but might play more in the future. I can get this for around $1500. Any thoughts or advice? I know from reading the board some hate Dell, but I have used them for work and they seem to be fairly reliable. Lastly, this is probably more machine then I need at the time, but I want this sucker to last at least 3-4 years without having to replace it. Thanks.
