next generation card always faster than today card..
if you have to wait, why not wait until the launch of GTX99999999 ?
if this card in the future is too slow, grab another $500, and upgrade your card again..
well he might regret it if he is only playing at something like 1280x1024 resolution and already has everything maxed with high frame rate. OP could you list your monitor(s) resolution and games you are playing/plan to play soon?
Well if you are able to play all your games pretty well I vote you should hold off till the new cards come out in 4 months or so. I mean the 600 series has already been out for about 8 months. Maybe its just me but I like to buy my cards at the start of the series and not right before the next ones come out.
