I have an Asus 6870 DirectCU which is starting to show its age. I'm looking to upgrade to a new card (a 270, 290, or something in that neighborhood), but I'm wondering if I would be able to use it simultaneously with the old card. They wouldn't be linked in Crossfire as I'm not sure that's possible. Would it work? If so, I have a few other questions.
I'd want to run 3 monitors off of this setup, so would I be able to use Eyefinity with this? How would this setup look in the AMD settings application? And how would it perform under a heavy load like a modern game? Would I only be able to run the heavy stuff on the displays connected to the new card, or would all 3 display connections perform at the same level?
The system is a i5 2500k on an Asus P8Z68-V LE motherboard. Thanks in advance.
