Recently Rage3D reported that the method in Crossfire capable cards used? to communicate to each other could be flawed, offering no higher than 1600×1200 at an unimpressive 60Hz. Speculation arose when the backbone to this setup was the Silicon Image Sil 1161.

Penstarsys.com has more information on this and is countering the argument, saying that ATI cards will probably not have such limitations:

"The receiver can handle 1600×1200 @ 60 Hz, which means that it can receive 60 frames of 1600×1200 pixel content per second.? When used with the output of the master card, this can give a theoretical maximum of 120 fps at 1600×1200 resolution when using alternating frames.? Most high quality 21" CRTs can usually handle a maximum of 100 Hz at 1600×1200, so using AFR with v-sync enabled, 100 fps is theoretically achievable (depending on the application of course).? Let’s look at other situations."
