my sister got a compaq at office depot for 400 bucks 250 gb hard drive 1gb ram lightsribe cd/dvd burner its really nice and so cheap, i have a compaq right now ( really crappy one spec wise) but it performs like a alienware
i doubt it would perform liek an alienware unless it is similarly configured and you aren't doing anything intensive. remember it's what's under the hood that determines performance though, not name. for your needs a 300$ cheep + a ram uprade would also be a possibility.
its not really nice. probably (if lucky) ddr-400, but probably (MAX) ddr-333. probably ata 100 hard drive. most likely a pentium 4 like 2.4Ghz. eh? that some where in the right place?
ddr333 coss more than ddr400 beleive it or not... so i am willing to bet it is 400. DDR400 has been out for like 3 years now.
