Double ? Don't think so. And it's probably only in crysis, link to the review anyways I'd like to see that.
I'd be suprised if the overall difference was anything above 20% at most and most of the time more than 5-10%.
Now you could say, YEH BUT 20% IS a lot, no it isn't, game at 60fps isnt any smoother than game at 50fps.
I wouldn't be upgrading anywhere less than 40-50% increase. Not at this price. Sure 5770 is an excellent card, but tbh it's nowhere worth it's price, it's hardly a slightly improved 4850 DX11 revamp.
You can get 4870 with same performance for less than half the price.
But then at the end of the day, it's your choice and you'll do whatever you want regardless of what others say.
I will personally wait for the 6xxx cards before buying anything slower than a 5830.
The 5770 was a good value for money when it came out, it's not anymore, unless you can spot 2nd hand one for around 80quid.
