Good hardware compatibility info?

[Tom Horsley]

Since my computer died, I'm looking at building a brand
new system, and I wonder about all the fancy new stuff
available in the hardware and linux support (fedora
in particular). Other than beating my head against google,
is there a good resource for researching this stuff?

I'm wondering about things like USB 3.0, sata 3.0,
UEFI BIOS, Sandy Bridge, i7 processors, Intel HD 3000
graphics, etc.
