I would like to know if I can put my Sound Card into my x4 slot and my Tv Tuner into my x8 slot. I would just simply like to know if I can run these.

Motherboard : ASUS Rampage III Extreme
TV Tuner : Hauppauge WinTV-HVR-2250 Dual Tuner PCI Express TV tuner
Sound Card : PCI Express Sound Blaster X-Fi Titanium Fatal1ty Champion Series
Graphics Card : Diamond Radeon HD 5970 (2)

A PCIe card will fit into a slot of its physical size or larger, but may not fit into a smaller PCIe slot.

Thank you very much but when I put the Sound Card in there would I have to tweak some sort of setting. Also this sounds noobish but I really don't think this is possible. A Killer 2100 Network Card into a PICE x16 slot. I know what you just said but I just don't believe this is possible so can you confirm that for me. Thank you for replying so fast btw, thought it would have taken me till tomorrow.

No setting need to be tweaked. A 1x or 4x will fit into a 8x or 16x PCI-e just fine. A regular PCI card however will only fit in a PCI slot. Think of the bigger sizes like adding extra pipelines for the data to travel. 1x = 1 Lane, 4x = 4 Lanes, if the card is smaller than total lanes of the slot that's ok.

Yep, that will work fine and you shouldn't even have to change anything in the BIOS.
