Hmm. Cant seem to find a manual on Jetways website. From what I can see in the pics on Newegg it looks like something that goes into a PCI-E slot. I would take a look at your manual and it shoud say what its for.
Its not that hard. My only concern is the Jetway mobo... Their website seems to be lacking for support options.
Color me biased, but Gigabyte or Asus only for me. They have both treated me well in over 20 builds for myself and friends. My 4 current machines run a Gigabyte p45, an Asus x48, an Asus 680i, and an Asus 754 (iirc). I think Ive used at least 15 Asus and about 5-6 Gigabytes over the years.
