get it, i'll hate you at them prices if you don't get it.
No not until there's another card out there that can compete against it. Right now a GTX is the fastest card there is so no major drop from it or the G80 line. Also sales of the DX10 are not that good really since few games only supports it and most of us are still in XP mode.
It would be nice to at least see an 8800GTX drop below the $500.00 mark, but I don't think you'll see it for quite a while.
NewEgg is selling the overclocked MSI 8800 GTX for $489.99 after $20 MIR.
