My case wont allow me to fit a 5970 in the first pcie slot with this mobo. However as its x58 and i get 2x pcie @ x16 would i see any performance decrease if i were to put one in the 2nd (lower) pcie bay? Its not a bad place to put a gpu now i've taken the hdd bay out. Would be nice to have a 140mm fan blowing straight onto my gpu
