Conclusion:
As you?ve just seen in the benchmarks, CrossFire?s key advantage over NVIDIA SLI is ATI?s Super AA performance advantage with the Radeon X1800 XT over the GeForce 7800 GTX cards. ATI?s redesigned compositing engine brings a massive boost to Super AA performance, resulting in little or no performance hit for 8xAA at lower resolutions. In a graphically-intensive game like F.E.A.R for instance, at 1280x960, performance is nearly cut in half for the GeForce 7800 GTX 512MB SLI setup, from 93 fps to just 42. Meanwhile, the X1800 XT CrossFire is cranking along at 51 fps, a drop of just 16%, or 10 fps!
.......
Until CrossFire?s infrastructure catches up to SLI, we have a feeling that ATI?s CrossFire technology will continue to play second fiddle to NVIDIA SLI despite ATI?s superior performance in higher AA modes. Gamers looking for the best combination of image quality and performance though should definitely consider ATI?s CrossFire solution. Because as it stands now, ATI?s got the edge over NVIDIA when it comes to this.
