Would $550 for the pair be reasonable?
I'll accept $550 for them.
Here's an XFX HD 5870 for $250:

Also, Newegg is out of 5830's... So options are dying down out there.
datathe: if you're selling two cards, there should be some advantage for buying them together. So the price should be *less* than buying the two cards separately. $550 is borderline, but you can try. Hardforum is a good place to sell, but you may need some seller reputation first (ebay, heatware).
