BTW, VirtualLarry, I just did an excercise on the ibuypower site. Custom configuration, lowest end AMD dual core athlon, removed all options. Added a 9800GT card. Total: $453 shipped, and it looks to include an OS license and warranty. I'd grudgingly accept that as a low res, low end, extreme budget "gaming" machine. But not a 4800x2 + 1950GT.
Let's simplify this discussion a bit.
Is the problem with calling this rig a "gaming rig", with the CPU (X2 4800), with the RAM (2GB), or with the included video card (would have been the X1950GT, except the 500W PSU I was going to put in has a 24-pin ATX connector, and the mobo uses a 20-pin).
So the actual build has an X1300 in, as a placeholder card, which I explained in my craigslist ad (Boston, search for "Hudson").
As far as I can see, except for the handful of games that really require a quad-core to play decently, every other game on the market will run, CPU-wise, on this rig (perhaps with a touch of overclocking, say 2.4 to 2.6). So I'm guessing the problem is with the video card. But if I sell it cheaper, and allow the end-user to drop in a "gaming card" (according to their definition), then where's the harm?
Edit: I should add, I sold an overclocked Opteron 165-based AMD rig with 2GB of RAM and a 9600GSO to someone for nearly $600 as a gaming rig six to eight months ago. I've had no complaints about it. Put Win7 RC1 64-bit on it, and it was clearly stated in the ad that the OS expires in Mar 2010.
Edit: I went to the ibuypower site and configured an Athlon II X2 240, 2GB DDR2-800, DVD burner, stock case, stock PSU, 9800GT 512MB, for $446 without shipping. Notably, this is also without an OS, Vista home basic is $86 more, and OS prices just go up from there.
