Looking at 7770 Crossfire Reviews on the internet,

7770 Crossfire is almost = one HD 6970 or HD 7950.

And... HD 7990 = 2x HD 7970

If you want to run Crossfire it is a best choice to get a mainboard with two PCI-E X16 or X8 expansion slots. (990X or 990FX chipset mainboards).

I hope this translates clear to your language.


FX-8350 @ 4.8GHz // ASUS Crosshair V Formula 990FX // Sapphire Vapor-X HD 7970 + Dual-X HD 7970 // Thermaltake Frio w/ push-pull (using Antec Formula 7 Nano-Diamond + Cooler Master JetFlo fans) // 8GB (2 X 4GB) G.Skill RipJawsX 2133MHz  // Corsair TX850 850W // Corsair Force GT 120GB SSD (OS) // Kingston V200+ 120GB SSD // WD Caviar Black 1TB // Windows 7 Ult x64
