The 5850 is no longer a good purchase. In SLI/Crossfire it gets smashed by the GTX 460. That 5770 you had is no longer worth anything in that you can't crossfire it, whereas 5770 crossfire would only have put you out another 130$.
Basically, that old 5770 you had is now a sunk cost in addition to the 5850. You spent more money on the 5850 than another 5770. If you crossfire, it helps, but it wasn't a good time to buy a 5850 in general.
The 6000 series is supposed to remedy that and will be out within two months.
but what i meant is is the sapphire 5850 vapor x a good choice. i live here in the philippines and here there is no store that sells the reference design anymore. all they have are the new coolers. i had a choice between xfx5850 which is not that popular here meaning i will have trouble reselling it. sapphire thats not vapor x , gigabyte is also not available here. considering my choices did i picked the right one?
