I think NV may have backed themselves into a corner if the info about the cost and yields of the GT200 chips is right. The margins are meant to be pretty bad already on the GTX280, I'm sure they're extremely limited in how much they can drop the price, saying that, I'm really appalled at OCUK's price on the 280s, how do they think they'll sell any when they're £70 more than they should be? No wonder they've got their 'no competitors' rule.They must think some people think OCUK are the only online store in the world.
