Hello all my fellow TPU geeks, i have a quick question about mixing cards in CFX. A few weeks ago my MSI Twin Frozr II 5870 broke down and i sent it back to MSI and they told me they could not fix it or replace it with the same card. Instead they asked me if they could send me a 6870 with the same Twin Frozr Cooler. I of course said yes because they already said it was all they could do. Now, i know that the two cards are similar in performance, although maybe not exactly the same, i did however read that they scaling for the 6000 series is better with multi GPU setups. What i am wondering is: How effective is the scaling if i were to pair this with a 6850? what kind of performance hit would i take as opposed to another 6870? Should i only pair it with another MSI card? I havent had a multi GPU rig since 7900's in 2006 and a lot has changed since then. Any help is great. Thanks guys!
