Oh, and yeah I've seen that review. The Quad SB-E is pretty lame, all things considered. The 3930k isn't the gaming beast that the i7-2600k (or it's overpriced, binned brother 2700k) is, but it single-handedly force-chokes all global warning doom-sayers when processing video encoding jobs.
Look at that bad bastard go!
I think the 3930k is where I'll go. And then when IVB-E comes out in a year or so, I'll swap the CPU and call it good.
I plugged the current RAID card into my x38 / overclocked Quad 9450 rig just to see what might be possible, and I've discovered that the PCI-E implementation on this board doesn't deal well with the throughput the RAID card can put through. I can put up some ATTO / CrystalMark / AS-SSD numbers if someone is interested, but these are NOT interesting.
Basically, the transition from one to two drives is roughly linear (as you'd expect), but it has a strong taper at the top end. Sure enough, I get basically no scaling with three drives, and I cannot even attempt benches with four drives as it completely locks the system. I'm pretty convinced that it's a PCI-E (chipset) issue, because benchmarks even on dual drives will make WDM crash during the high-queue depth 4K random tests. When using three drives, WDM will start flaking out during the transfer tests and pretty much stops responding entirely during 4K tests. On four drives, it just reboots the system about halfway through the first transfer test.
Ye ol' 4-year old X38 chipset just wasn't meant to deal with this kind of abuse
