Gigabyte 790FX DS5 motherboard question

[snowmanman]

Hey all,

I've got a Gigabyte 790FX DS5 mobo and I was tweaking some stuff in the bios when I noticed an unusual option. The option is called Xpress Route. It's disabled right now and it's discription is that it improves video card performance when enabled. I searched all through my mobo manual and I can't find anything about this option. I've googled it and found nothing.
I just hesitant to turn it on because it's disabled default for a reason right? Does it cause instabilty when enabled?
Anyone have any info on this Xpress Route option?
specs: Crossfire 3870, Phenom 9600 2.3ghz, 2gb(1066) ram

leave it off, run a few 3dmarks.
turn it on run a few more.
comapre the results.

does that have OBG? I understand some OBG can crossfire with some low end card for better performance. maybe thats what that is.
