*** Official Radeon HD5800 Series Overclocking Thread ***

[madriddistas]

I have tested both the HD5850 and HD5870 at 1000/1250 and i could barley notice any difference in performance , Stalker had like 10% advantage with the HD5870 , otherwise there is like 5% difference across the board for 30-40% more $$$$

What's the voltage for both HD5850 and 5870 probably the former should be pumped a bit higher, yes?

If both done in stock HSF I might go for HD5850 but need to know the voltage 1st since have to worry bout the electricity bill :P

Both are done on stock HSF with fan at 60%
Amount of Voltage will vary from card to another , my 5870 sucks and needs 1.32V to be 24/7 stable for games but it fails at Furmark with that Voltage , the HD5850 only needed 1.27V but your milestone may vary

How much $$ per KW you are paying coz they use lots of power when overclocked
