Isn't Quantum 3D (not quantum the hard drive maker, Q3D made the Obsidian X24 V2 SLI one a single board) using those multichip VSA boards for their AAlchemy line? For applications (like RT sims) that need massive fillrate and have the option (as the name suggests) of massive Anti-Aliasing, this board would kick some major arse, no T&L? But who cares they probably have 4 or 8 way Xeons for the T&L end. That thing is damn sweet...it's not exactly for gamers though.
You aren't going to buy an 8way VSA and put it in a 17" midtower...
