PhoenixRising:
To be honest, I wouldn't recommend getting any card right now. New cards will be coming out from ATI very soon and they look pretty amazing so far with around double the performance of the current cards. The prices for the current gen cards will drop like a rock.
There's never a right time to buy a 3d card - buy one when you think its a good deal,
theres ALWAYS something new on the horizon in the pc world and you'll nearly always end up losing a small fortune, you'll just end up faffing around for months getting more and more confused finally buy one - then 2 months later a new one will 'be in the pipline' or a gtx/gtxxx/gti version with more ram/quicker ram.
I've given up trying to keep up
