How does any of that make the RX200 system worth paying $50 more? Just going by Newegg's prices (and ZipZoomFly is probably cheaper on most of this stuff):
Biostar or Soltek K8M880 IGP board = $65.99
Sempron 2600 (Socket 754, 90nm, 1.6 GHz, 128K, retail) = $79.98
$145.97
If you want to save money on an office system with IGP, this seems decent.
Biostar NF3 250 = $57.50
Sempron 2800 (Socket 754, 90nm, 1.6 GHz, 256K, retail) = $90.98
Radeon 7000 (64MB, DVI) = $33.00
$181.48
If you want to spend $40 more, have a real video card with DVI and double the CPU cache, this is a good deal.
Epox NF4 Ultra = $92.99
Athlon64 3000 (Socket 939, 90nm, 1.8 GHz, 512K, retail) = $146.99
Radeon 9250 (128MB, DVI) = $42.50
$282.48
Here you're getting a really good chipset and a really good CPU for a good price.
MSI RX200 board = $94.49 (out of stock)
Athlon64 3000 (Socket 939, 90nm, 1.8 GHz, 512K, retail) = $146.99
$241.48
Now where exactly does this setup fit? It seems like the worst of all worlds. If you think you need a 64-bit system, this questionable motherboard setup with an IGP is only saving you $40 when you could have a real NF4 chipset with a real video card. If you're trying to save money, you could get a Socket 754 setup for $100 less.
I don't see in what reality the Radeon Xpress 200 is a good idea.
Like I said, I would go as high as a passive Radeon 9600 on an office system if there was any chance of it being used, but if you're going to argue about integrated graphics and shared memory, I'll keep the price down in my examples.
