Well, sure, but i was referring as list price for cpu doubling suddenly if you
go against IBM markets and such stuff. Bet what will happen to G5 availability
if we were to release a machine in the imac G5 class ?

Sure, but do you really need that ? For a desktop / developer machine ? I
suppose the pegasos as it stands can go upto 2GB of memory, maybe even 4GB if
there are 2GB sticks available. Theoretically the cpu can address upto 8GB,
but the current design has not the >4GB cpu-to-motherboard lines wired. Still,
you could use stuff in excess of 4GB, or 4GB-io-space, using some kind of DMA
buffers on the northbridge or whatnot, since the marvell discovery II can
address 8GB itself.
