How would these do in CrossfireX?

Im thinking of getting 2 of these http://www.asus.com/Graphics_Cards/HD77702GD5/ to use in Crossfire mode. How would they do?

Why not just get a single 7870? It alone is about twice the performance. Eventually you could get 2 7870's. I mean 2 7770's would be somewhere between a 7850 and a 7870 when you take scaling into account. In some games 2 7770s outperform the 7870 by 1-3 FPS. It also matters very much on the resolution, and what games you'll be playing.

And it won't scale very well in some games, probably indie games most commonly, because they don't get driver optimizations from AMD or Nvidia. CrossFireX (And SLI) sometimes perform worse than a single card if they aren't optimized.

About 15-75% better than 2 7770's depending on the game. I'm not sure of cost but a 7850/7870 would likely be a better option.

I'll probably play games like is city and far cry 3 on 3 24" monitors

Yeah just get a 7870. I've a Sapphire 7870 GHz edition OC- I got it for $50 cheaper brand new - Call it immense luck. It handles everything very well, but at 5760x1080 Don't expect to run everything maxed. A single 7870 will run all games fine on medium-high at very playable FPS.

I'm preferably looking for a pice 2 card

Get a 7870 XT (tahiti LE) it's faster than 2 7770s & costs just the same, plus you can add another one in crossfirex down the line, you also don't have to deal with scaling and driver issues.

It doesn't matter. The 7870 maintains a solid 95-99% usage even on pcie 1.0 (I have an old mobo and it runs well).

Don't get a 7870 GHz, get a 7870 XT instead, it's just as fast as the regular 7950 and overclocks very well.
