Asus is my #1 pick for motherboards, but one of my last for video cards. OTOH, MSI is pretty high up the list for [nVidia] video cards, but I do not trust their motherboards.
I haven't bought (and wouldn't buy) any Jaton video cards, and Diamond is on my personal "Do Not Buy" list for a raft of reasons; of the cards I remember, I had good results from HIS (4-5), XFX (4), Powercolor (2-3), and Sapphire (2-3), and from the one MSI (GTX460) I bought.
