I'm building myself a new gaming machine, i already picked out the mobo and most of the components but i do have a question to ask. I'm getting Intel's D975XBX2 board, now according to Intel's wedpage this board has 3 PCI-E and 2 conventional PCI slots. But they dont tell you what type of PCI slot it is, just that it is coventional. I want to get an X-FI sound card which requires an available PCI 2.1 slot, but since i dont know if the slot on my board is 2.1 or 2.2 or something else i dont know whether i should get the card. I've been trying to find this out by going to intel's site, i looked through the manual but it still cant get an answer. So here's the questions: does anyone know what kind of PCI slot this board has? what does coventional mean? Will this sound card work with this mobo? I know this may sound stupid but this is my first build and i still have much to learn. I'll be grateful for any help.
