Just compared a 5800 bios with a 5800u bios and found speed tables to be same, 2D is 300/600, Throttling is 400/800, and 3D is at 500/1000.
So maybe temps wont be an issue unless for overclocking ?
You are correct. The 5800 uses DDR clocked at 400mhz(800mhz effective) and the 5800U uses DDRII clocked at 500mhz(1ghz effective). Isn't DDR faster if clocked to the same speed as DDRII?
