Anyone know much of the difference between the 2? This is the MB i just ordered.

ASUS P8P67 Deluxe LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 Intel Motherboard
 
ahh ok, thats not really a huge difference.. but i'm good with that. I was going nuts about all this x8x8 and x16x16 lol. thanks man
 
With two top end cards, two 16x pcie slots is 1-5% faster.

That was true on 1156 and 1366, but does anyone know if its still true for 1155?

For 1156 and 1366 the PCIe lanes ran at half speed, with 1155 they run at full speed, so an two 8x 1155 slots will have the same bandwidth as two 16x 1156/1366 slots right?

I would guess with the current generation of video cards you won't be able to tell a difference between 8x and 16x on the sandybridge platform.
