AreEss said:I'm actually very disappointed with the Mac Pro. Yeah, great. Quad processors. FB-DIMMs, that was an Intel design call - not Apple - so I can't blame them there. Finally, more than two hard drives - about freaking time! Like the Firewire configuration. But the 4 16x-mechanical slots was a really, really bad judgement call on their part. Hell, I'd almost call it deceptive, because they hid it in the fine print.
"Configurable bandwidth that mechanically supports 16-lane cards"
Mechanically means the slot has the physical room only. Nowhere does Apple say how many total lanes they have. Based on the features (533/667 FB-DIMM, Woodcrest) and timing, it's almost certainly an Intel E5000X (Greencreek) chipset with the 6321ESB I/O hub and without the 6700PXH PCI Hub. Why? Only chipset out right now that supports Woodcrest and FB-DIMMs. Greencreek only has 20 PCI-Express lanes. That means those four 7300GTs? They're running with a whopping 4 lanes. That also rules out dual 7950/4500X2's, which require 16 lane electrical per still. (Apple may get nVidia to change this in BIOS soonish.)
Right up to the point I saw the PCI-Express problem, I was seriously considering the Mac Pro. But seeing that, I'll definitely be passing on this one. I'll wait for the Mac Pro that actually has the PCI-Express lanes to support it's physical slot configuration - hopefully next year.
For alot of the Mac Pro market it might work though. I will fully admit you are far more an expert on workstations than I am, so if I am completely off on anything let me know, but the Quadro cards mainly come into play on high end 3D rendering applications and CAD type software correct? A lot of 'pro' Mac users mainly do Quark/Pagemaker (or what is it now, InDesign? Pagemaker was a better name...)/Photoshop and FincalCut(Pro) none of which really need even one Quadro, much less two.
