Best PCIE slot for OCZ Revo on P8P67 Deluxe board

[shotosan]

Built a SandyBridge system with an Asus P8P67 board. I have an AMD Radeon 6950 graphics card, and an OCZ Revo SSD PCI-4x card.

The mb has three PCI-16x slots (the third runs at 4x). I'm wondering what is the best slot to put the OCZ PCI-4x card in?

Right now I have the GPU in the first PCIE-16 slot, and the OCZ Revo in the second PCIE-16 slot.

I could have put the SSD card in the third x16 (@4x) slot and left the second one open but it looked like it had less IRQ sharing in the second slot. Does this matter?

Nope. Not with PCI-E. Someone wrote this long ago:

PCI Express uses in-band message-based interrupts, not the side-banded
level-sensitive interrupts of PCI & PCI-X Mode 1. Oodles of MSIs, no sharing
required...
