Nonsense. Any PC must be expected to have memory and/or PCI cards added.

There's worse. I remember years ago having to fight to get a Dell over a Compaq that was $1,500 more despite being far inferior (e.g. 486 vs. P90), not to mention that, IMO, desktop Compaqs were, and still are, garbage. "You get what you pay for", I heard, always from people who had *zero* clue about computers. I've had great success with generic hardware.

On the other hand, the i7-875 unlocked is cheap and allows o/c by use of multiplier. But no cheap memory there, need 4GB parts. I'm tempted to build a host machine with Xeons and ECC memory, slightly more reliable and all, but I think slower. Lots of ways to go, each with a drawback. :-(

For both cost and power efficiency reasons vendors seem to sell machines where anything more than a memory upgrade puts it out of power. Add a disk, marginal, hope you can power on spun down to avoid surge. And that 200w super gaming video card? Not on the machines intended to let a casual user get on the net, or a clerical worker do data entry or update a few things using the system as a terminal. Seriously, I see stuff with 300w, even 250w power supplies, and as shipped they have 50w of headroom if the voltage stays up. Honest, lots of vendorsmaking them, and they work fine when used as intended.

When the chip had just come out, I saw a geek buying the parts to build a computer for a chess competition. Who else buys machines with these chips? I can use the memory bandwidth, but, for most, the triple channel arrangement is overkill. All you really want is the extra memory slots. Just glad to have it, wish 4GB sticks weren't so expensive.
