Careful...you're mixing technologies (PCIe vs PCI).
Here's the slot definitions (starting near the CPU and working down):
Slot 1 = no slot
Slot 2 = PCIe x16, gen2
Slot 3 = no slot
Slot 4 = PCIe x16, gen2
Slot 5 = PCI v2.3
Slot 6 = PCIe x4 (x16 mechanical), gen1
Slot 7 = PCI v2.3
I think the Bearlake-X chipset was limited to 32 lanes of gen2 PCIe support, which correlates to the above data.

actually i was being lazy using PCI/e, meaning PCIe and PCI - in future i won't take shortcuts
thx for the clarification - pity about the PCIe x4 slot, but that's how the cowpat crumbles
i asked becaue i ordered a unit for the 3.5" bay that has a card reader and 4 USB 3.0 ports and it plugs into a gen 2 PCIe slot, which in this case will mean my extra video slot

unless you're planning to constantly saturate the card with more than 1000 MB/sec worth of data transfers then the x4 slot is fine. PCIe 2.0 devices are backward compatible with 1.0 slots.
for your purposes i'd be willing to bet this is a non-issue. choose whichever slot makes more sense based on location rather than maximum sustained transfer speed.

brilliant - no sacrifices required - appreciate the reality check/low down on the functionality of the slots and i think that level of saturation will be well beyond my SOP: as always, much appreciated
