Hey Bill, thanks for your reply!!!! Yeah option 1...... I think we
will do whatever it takes to avoid that route. I don't have a good
reason for it, it's just preference. Great manufactures/produts....
etc..., we just like the flexibility we get with how things are setup
right now. Not to mention extra rack space! Option 2 is exactly what
we are looking at. But before that, we are looking at upgrading to a
PCIe 3 x8 or x16 as mentioned earlier for that "small bump". If we hit
25% increase in throughout then that would keep the barracudas  in
suits at bay. But for now, they are really breathing down my back...
