as I thought, 1156/1366 users don't really get much from a SB upgrade for the money they had to dish out. To be truthful I think a decent 775 quad running 3,6+ or a AM3 quad running 3,6+ can probably hold out a bit until 2nd gen BD or Ivy Bridge to upgrade. On a personal note, I'd say if you are on a quad, the next upgrade that makes sense is probably a 6 or 8 core. quad->quad just don't feel like a real upgrade esp. if you have to get new board or even memory. But of course if you need the extra performance now, there's no point waiting.
