Decisions, decisions....

So, I'm looking at buying a laptop with the money that finally came hrough from my cashed-out 401K. Mostly because It means I'll be able to have a workstation I can use in the living room whil I'm minding Brenna late at night, or can take with me to get out of the house to do some work. HEre's what I'm looking at, for a $598 price tag:

So, hardware junkies- am I actually looking at a decent deal? I realize the memory needs some help on it, and well, I'm prepared to pay the $40 bucks extra for a DiY memory improvement on it. This is after all, more for a work station than a portable gaming box. The one theing I don't know too well off the top of my head is processor speeds- just what is that Athlon chip comparable to in terms of intel hardware, or for that matter, can anyone find just the straight Mhz on it? But yeah, beyond that, is this a decent deal? I'll keep the question open for input until I hit the sack tonight, at which point I'll either buy or not buy it. So in the meantime, comments much apprciated.
