Even at $650, it's a bad deal. CF 5850s are a much better option. ATi's highest end card sucks for value. nV's highest end card sucks for value. Intel's top CPU sucks for value. AMD's top CPU sucks for value. If you don't see the truth in all those statements, you are a fanboy of the company you take issue with.
I'm not sure about this. Poisoning the well seems a poor strategy for trying to establish your point.
You're playing with the word "value" and I think we need to define that better so we're not equivocating. The way I see you talking about value involves relating performance to cost, correct? A person looking for value of this type is looking for:
(A) The best price to performance ratio
but we need to add a couple qualifications
(B) In a current product line
(C) Relative to the specific needs of the user
The need for B is obvious. Some older products offer much better price/performance ratio than the current generation since their prices have been slashed. We need B to rule out those products that have a good ratio but simply aren't in the running for because they are too old to count anymore.
The need for C is related to the point I was posting earlier. Value is partially dependent on the kind of thing I'm looking for. A 5850 offers me NO value at all if I am not in the market for a video card or if it lacks the feature or level of performance I am looking for. If I am in the market for the highest-performing product out there, then once again, there is NO value in a 5850, it does not have what I am looking for.
In short: There are other prudential reasons for purchase that modify the meaning of "value" even if it is taken as (A).
Admittedly, the market for those people looking for best-in-class is small. A small group does not imply a negligible group, nor does it imply a group of "fanboys". It simply identifies a group of people who have a different (C) than you do.
