I bet the card would run just as fast on x8 PCIe 2.0. I'd like to see the PCIe lanes cabled off the mobo so you could customize how many lanes you use and how many slots or what sort of slots and the spacing of the slots-to give you as much room as you like; maybe a double case design with expansion slots front and back and a peg board so you could move the slots.
Right now, you get what you get, a fixed number and type of slots,hardwired PCIe lanes, and there's no room for the cards you do have slots for.
I bet the price of women's shoes or maybe a nice purse and some frilly underwear, compares better. It's just not fair......or is it? God save the Queen? Good God ya' all!!!
