Here's the question. With a choice between the 300a vs. the 366a (Slot-1), which should I get? I have a place where I can get the 300a for $65 (Costa Rica) or $70 (Malaysia). The 366 runs about $80 bucks or so. I've heard that some 366's can get to the big 550, but that the success rate is fairly low. This is going into a brand new system, so the PCI devices *should* be able to handle a odd bus speed (I'm getting PC100 RAM).
