Yesterday we took a look at the XFX R7870 Black Edition OC and really liked it. It seemed to fall into a nice sweet spot between price and performance. Today we are going to take a look at what looks to be the same card but bring the R7850 not the R7870, there are a few key differences. There are major differences in both power usage and compute performance between the two cards. I am really curious how this will translate to the performance and ultimately the price/performance that make the R7870 an idea card to pick up.  Will the R7850 be an even better deal or a card to pass on?
