[citation][nom]dgingeri[/nom]Personally, I like the look of that SB-EN chip. It's not as overblown as the SB-E: 3 memory channels, 8 cores, 20MB cache, 24 PCIe3 lanes (3 x8 slots would be nice for 3 way SLi without overdoing it, maybe using a bridge chip to change those to x16 PCIe2), and a single QPI link. It's meant for single socket designs. We already know the quad channel memory config doesn't help anything. Triple channel memory would be fine. (Works fine for my 920.) I just hope it's not too overpriced.[/citation]
I really don't see the point of talking about the advantages / disadvantage of these platforms from an end-user perspective as these are meant for servers. Quad channel is really most beneficial for various server uses.
Going back to the end-user, enthusiasts finally have the opportunity to create a rather large RAM-Disk thanks to 64gb support of the SB-E platform (thanks to quad channel config).
