I got in on the Powercolor 7850 deal for $230, but the cooling on the card really seems insufficient. Overclocked to 1150mhz on the core and 5600mhz on the memory I'm sometimes hitting 85C under full load which seems way too hot to me. Do you guys think I should take off the heatsink to make sure that there is thermal paste and to verify that everything is seated properly? I might just have to go with aftermarket cooling. Even at stock this card hits 75C under load.
