That's because what we really need is a RAMDrive chipset that plugs into the PCI-Ex bus. When the RAM drive is capable of moving several gigabytes per second is when you'll really feel the difference. If someone offered me a PCI-Ex Card with extension cables into a 5.25" format box (like the one above), which could take 6 sticks, and saturate PCI-Ex 1X, I'd buy it tomorrow.
