In Game Performance
In game performance between different game engines really varies depending on Nvidia and AMD, each manufacture works very closer with different game developers to try to have the best optimization. Because of this it really depends on the game that you are looking to play as you will see in our results. For the most part the HD 7870 FLeX came in just below the GTX 580’s other than in a few games that are little more optimized to AMD cards like Shogun 2. We did also see a few interesting results when comparing HD 7870/7850’s along with the overclocked variations. In a few cases the overclocked HD 7850 outperformed this card. I believe this is a combination of the overclock and driver changes that we have seen lower performance in games slightly. We will actually be doing a small driver comparison soon, keep an eye out for that as well.
Anyhow what really is important with the HD 7870 FLeX will play every single game that we benchmark with gave us playable framerates (30 fps or more). In almost every one of those cases they were well beyond playable meaning over 100+ FPS. This is just in 1080p of course, pushing three times that resolution (for Eyefinity)is going to mean a few of the most demanding games will need a little adjustment in the settings. But games like dirt 3 will play fine.
