Hi all, new to the forum but there doesn't seem a better place to be asking this. I'm contemplating upgrading my 6670 to a 7850 2gb as the benefits obviously speak for themselves, but I'm wondering whether to crossfire my A10-8500k with the 6670 instead? Is the performance of those two components comparable to a single 7850? And are there any negative effects to the APU when it's crossfired and not running as a standalone CPU? Thanks in advance for any input.
