Help me choose HD4850...

I heard ATi HD4800 series is burning... its okay if the performance is burning others Card, but if the temp burning, I do concern...

So I'm searching for a good cooling like this... Do you guys think its "a lot better' than the reference cooling...

MSI R4850 http://www.overclockersclub.com/reviews/msi_r4850/2.htm

or HD4870 any brand... I know HD4870 is better, but my rig only have 450watt PSU and my monitor is 19'inch...

Thanks for Help...

That's a sloppy review:
-They didn't say what drivers they used (they used 8.6 for the Sapphire)
-No graphs for the temperatures
-No temperature comparison with reference cards that use the fan fix

As long as your case has two 120 mm fans (front and rear) and you use the fan fix, the reference model is fine. My card idles at 47-48C with 35-40% speed, and under load never goes above 70C with 55%.
