In fact nobody accused you that you posted illegaly tuned benchmarks
by using the lowest possible resolution. As it happens this wasn't the
question. 

Normally what you get as benchmarks is material published by the
vendors (how have no interest of showing any weakness of their own
product) or magazines, which are largely DOS/Windows based, and hence
try to find the least common resolution between boards. Until recently
this was either 640x480 or 800x600. And in these lower resolutions you
simply cannot see this problem described with DRAM vs. VRAM that
clearly. If you then think about the fact that most people using X do
1024x768 in the highest possible refresh rates, these benchmarks are
pretty much meaningless (besides the fact that they are mostly measure
with drivers that were tuned especially for MS-Windows and some
benchmarks, who are very easy to fool). As far as I know up to now no
HW vendor yet publicates the XS3 xstones rating for his board ... They
are mostly not intrested in X-Windows as much as they are interested
in MS-Windows.

And one thing people shoudln't forget this that there are two new
developements in the market:

	a) people are starting to use 1280x1024 (110MB/sec)
	b) chips using 64 DRAM buses start to appear

But still VRAM will have a speed advantage over DRAM. And if the price
difference is that inferior as $50, one should really think about it.
