Okay I officially love wikipedia as it has been a reliable and 99% accurate
(despite what haters may say) about just about everything in the universe...
PCIe slots come in a variety of physically different sizes referred to by the maximum lane count they support, ie. x1, x2, x4, x8, x16 and x32. A PCIe card will fit into a slot of its size or bigger, but not into a smaller PCIe slot."
alrighty, I wont cut out PCIe2.0 of my newegg power searches now. This should make life much easier looking for mobos now.
thx
