Hi, I don't really know that much about the overclocking or the the workings of a motherboard except the basics, so this may seem like a stupid question but... I have a AGP and PCI-E hybrid motherboard fo intel skt478 and have recently bought a PCI-E card (x1800GTO) to replace my broken agp card(9600PRO). But then I find out from my motherboard manual that the slot is PCI-E x16 (x4 mode) which is really annoying because ASUS didn't mention this atall until you look in the manual, they market it as PCI-E x16. Anyway, what I was wondering is, if the x4 makes a big difference, for example if it was x16 it would run 4 times better, or if it doesn't really matter? Also, if it is a big deal, is there anyway of getting it to run at x16 by fiddling about atall? Thanks, Any reply is appreciated.
