dell 3000 vs 4700

I've bought both the 3000 and the 4700. It all depends on what you plan to do with it.

The 4700 is, without a doubt, a better machine for not a lot more money. Do yourself a favor and get the 4700.

I'm planning on getting either a dell 3000 or 4700 to replace my aging 550mhz which is having problems redrawing the screen and occasionally freezes for 10 sec to a few minutes. I'm thinking the 3000 dell is really all I need but the 4700 has faster memory & hyperthreading both are 2.8 mhz. the 4700 gives a choice between the 17 inch E173FP Analog Flat Panel & 17 inch UltrasharpT 1704FPT Digital Flat Panel. I buttume the ultrasharp is much better but since I've never seen it don't know.

What would people recommend ? I've had my dell 550 for 5 years and think I should just get the 3000 and maybe in a few years upgrade to whatever is available.

Thanks, Chris
