You're one of those selective reading types. Always a pleasure. Till next time...
And you have tunnel-vision. There is one 4890 on sale right now on newegg, and it's out of stock. The 5000 series offers more than performance over the 4000 series. If you can't see that then don't buy one. But don't assume everyone has your exact needs and wants, you are not the "galactic supreme consumer."
