Alright, so I was about to buy a 5850 for my new build which i will mainly be gaming on, and i just found out that the 6870 was just released and is cheaper than the 5850. I was wondering which one would be better for me to buy. Is the 5850 better than the 6870, or is it the other way around. I'm probably not going to do much overclocking right now and i won't be using crossfire either, so I was just wondering which one i should go for.
You most likely have the reference model of the card. All of the initial HD5850 were the reference model and they all had voltage control. It was later on when the manufacturers had some time to design their own PCBs and ship non-reference cards that most(apart from Asus and MSI) dropped the voltage regulator from the design as a cost cutting measure.
