Would you like it if Sony started producing CELL chips for PC?

[Kynes]

You should make several modifications to the PPU and the number of them to make a variant of cell suitable to PCs. Several out of order PPUs (branching, integer work) paired with SPUs (number crunching) could be an acceptable processor for an end user computer. The problem is that you have to migrate to a new architecture, and you don't have the critical mass of users to impose that change.

DX10/GPGPU isn't that important yet, and has millions of potential users, why a computer with a Cell's architecture processor should triumph?

I think the problem here is that Cell (and PS3's architecture in general) has an halo of mysticism. A lot of people believe it's the second coming, the same way emotion engine and graphics synthesizer were underpowered related to the hype created around them.

Sony PR guys must be very proud of their work reading threads like this one.
