HD 7770 crossfire in x16 x4?

Will I be bottle necking the 2nd card If I run it in an x16 slot at 4x speed. I've already got it so please don't tell me to get an HD 7870! Thanks!

  1. Not really. You may lose like 5-10% performance. That said, I do not recommend it. CrossFire HD 7770 is already weak in general. If I were you, I'd try to sell the HD 7770 and upgrade to a better card. The CrossFire is weaker than a single GTX 660 or a single HD 7870,
  2. Here are some of the games that I play: Dirt 1,2,3 and showdown bf3 mw3 Crysis 2 and starcraft 2. And in these games the crossfire set up cripples most of the higher end cards and is only 5 FPS away from the 7970 in dirt 3 at ultra in 1080p. By the way I'm 14 so I'm not some enthusiast or anything.
  3. So yeah do you think I could run those at ultra 1080p?
  4. At what resolution?
