Got a question, what mobos support true PCI-E 4x/8x throughput of the secondary slots? Talking non-SLI boards and Intel Chipsets (not NVidia).
Here's my concern: With the hype of PCI-E 16x for graphics, there are a number of mobos with additional 1x, 4x, and 8x slots. I can't find much information, but I'm worried that they are routed through the limited PCI 32bit controller bus. Limiting to 132MB/s. It would make sense for manufacturers to cut corners to do this.
My goal? High data throughput using the 4x PCI-E slot. I was dead set on a PCI-X 64bit setup, but Supermicro is about the only one that makes one with a decent PCI-E and 775x socket. And I haven't had much luck with Supermicro's customer support or products.
Here's the card I'm planning on at the moment:
Promise SuperTrak EX8350 PCI-E 8-port SATA RAID Controller for a RAID5 setup
Current plans are to start with five 500GB Baracude drives in RAID5. This will easily exceed the 132MB/s limit of PCI. Hence why I am looking into PCI-E 4x or 64bit. I like the idea behind PCI-E 4x.
Does anyone know if the Asus P5WD2 Premium board's 2ndPCI-E slot that supprots 4x is true 4x? Or just hype that is forced through the PCI's standard bus?

I'm getting close to putting togather my MCE machine that also will act as my file server. As you can see in the signature, I don't play when it comes to my personal machines.
The mobo is still up in the air, but current requires for it are:
- One PCI-E 16x slot (graphics)
- One PCI-E 4x or 8x slot (data)
- Two PCI 32bit slots (at the least, 3 preferred)
I prefer the Intel 955x chipset as I have a number of these chips around here. And I haven't had much luck with NVidia's chipsets. No, I don't care about SLI for my MCE machine. It won't be a highend gaming computer.
The current picking is the Asus P5WD2 Premium as I've used this and the P5AD2 before - at 4.2Ghz. I won't be overclocking much since I'll be running low-heat versions of the 775 chips with fanless HS and custom heat ducting for the airflow to be effective across the CPU's HS and mobo's HS. Drives will be in seperate enclosure.
Also since the release of the newer "True SLI" boards, I suspect the people with P5WD2's to get rid of theirs cheap soon. Hey, I just don't throw money at my computers. Yeah, I may spend a lot but I research for the best price and products first. And there's good reason for me starting at 2 TB of storage.
