This is a really nice setup and for around $700 total you're getting some amazing power. We didn't talk about it heaps during our graphs, but comparing the setup to the more expensive HD 7900 setups in CrossFire, the results are quite interesting. While for the most part we can see the $900 HD 7950 CrossFire setup comes in about 20% faster than the HD 7870 CF setup, when you start to look at the numbers, you can see there's little difference between then when it comes to our games being playable.
Metro 2033 is one of the most intensive engines on the market and you can see at the highest resolution we got a 79 FPS average out of the HD 7870 CF setup and a 99 FPS average out of the HD 7950 CF setup. On a 2560 x 1600, 60Hz monitor, Metro 2033 is going to feel near identical on both machines making the extra $200 investment hardly worth it for some.
If you want to max out in game settings at 2560 x 1600, I'd suggest the HD 7870 CF setup over the HD 7950 CF setup due to the overall better value. With that said, though, moving to the HD 7950 CF and HD 7970 CF setups is still extremely worth it as we start to move into AA and AF territory or Eyefinity resolutions. If you're only gaming at 1920 x 1080 or 1920 x 1200, though, the HD 7870 CF setup is going to handle games at native resolution extremely well along with the ability to turn on AA and AF.
While expensive, the HD 7870 CF setup sits in a good position between that $500 and $1000 mark. If you want to run absolutely maxed out details at 1920 x 1080 / 1920 x 1200 including AA and AF it's a truly awesome setup that represents the best value for that kind of gaming experience. If you also want uninterrupted 2560 x 1600 performance with game details maxed out and depending on the game itself having AA and AF as an option, it's also another really good choice.
At just $150 more than a single HD 7970, there's some truly amazing value to be had here. If your board supports CrossFire and you're already look at the $500 / $600 market for video cards, it would be really worth considering the HD 7870 CrossFire setup.
The bottom line is that CrossFire doesn't have the same ill effects as it did years ago when we saw it launch. Combined with the fact that AMD are offering us regular driver updates that fix issues, it's just a great setup to have.
