I just gonna overclock it and enjoy until then... Also I heard that the fan noise of the 5800 is really loud even when its idle. Only thing I dont get is how does the 5800U have a huge lead over most 5900 cards in benchmarks??
The core of the 5800U is clocked at 500Mhz while 5900s are clocked at 400Mhz. Quite a lot of extra horsepower and only begins to fall back in high levels of AA/AF when memory bandwidth becomes the limitation.
