It looks like the "package" prices are much the same here (when the exchange rate is taken into account).
The system you describe Darkhorse, at Walmart for $998 is around $2,000 here. A big slice in anyones language.
I've got a Compaq and have been thru the mill, but I'm much the wiser for it.
My computer shop bloke, who also puts together systems "made to order" has quoted me around $400 ($230 US) to make my Compaq into a 1.4 Mhz 512 RAM with Gforce MX440 (I think).
If you don't know what you need, you tell him what it's going to be used for and he will give you your options.
He has quoted me $850 ($500 US) to make up a 2.0 GB, 512 RAM , 30 GB HD, Ge Force (not sure of model but better than MX, 64mb). With this I just get the CPU.
I'm sure there are shops there that do this too, probably most of them, as it seems to be the way everyone (who knows) is going.
As was said (in not so many words), the "beautiful, neat, nicely boxed and well advertised "packages" are for the masses with more money than sense. Or perhaps, more kindly, people who know nothing about it, learning seems too great a hurdle, and think they are getting the most up to date (for what?) machine (especially when they come with tons of useless software). Case in point, my wife. ;D
The RAM problem with Compaq is complicated. I have gone through it and now know what went on and why. I solved my problem, but it took so long because Compaq made use of "old style/double side Ram chips that looked physically exactly the same as new style/single sided chips (they were available for only a very short time). All I needed was just to install old/double sided even though they didn't look the same. Thank goodness you can get them in 256MB.
Anyway................good luck, but don't buy another HP/Compaq. ;D
