Bottlenecking or not using the below modbus's with HD6970CF?

[dudeguzman]

Am I bottlenecking any thing specifically with the PCI espess slots using the below modbus? I will be running a i7-2600 cpu with proper sized power supply.

I will be purchasing a ASUS HD6970 video card (specs below). I will be crossfiring it with another identical card with in weeks.
