One more thing: SLI versus CrossFire. Oy. In certain games, ATI simply kicks butt. Its performance with one Radeon HD 4870 X2 simply walks Nvidia’s GeForce GTX 285, despite the fact that the two models we used are priced similarly. But add a second, and in some cases SLI gets close to doubling performance, while ATI not only fails to scale well, but outright loses its lead. Left 4 Dead, Grand Theft Auto, and Crysis are three examples. ATI still wins out in S.T.A.L.K.E.R., but SLI buys more performance for Nvidia. ATI simply dominates Far Cry 2, no matter which way you cut it. Even still, we'd like to see ATI match the scaling Nvidia is getting from SLI. At least then our point that gamers are better off with a second graphics card versus a pricey CPU would be easier to drive home.
So according to this then SLI scaling is better than CrossFire with Core i7, Core i5?
