The Powercolor card runs at around 85C under load even moderately overclocked, which is way too hot IMO. I installed aftermarket cooling on mine and I'm happy with it.
Direct Canada has that card for $230 with free shipping by the way.
The 7850 is better due to higher overclocking potential, more vram, less heat, less noise, and less power consumption.
I would recommend an Asus 7850 though. They have the best overclocking tools and you're guaranteed that the voltage is unlocked with the DC2 version, plus it runs cool and quiet.
