The NVIDIA GTX 280 is easily the fastest gaming GPU at the moment and we thought we’d find out how well it does in a dual card setup. From past experiences, we’ve seen that SLI or Crossfire add quite a bit of overhead (SLI especially) and doubling the GPUs certainly doesn’t result in doubling the performance- far from it actually. We already had nVidia’s reference card and thus, when we received the ASUS GeForce GTX 280, we wanted to see how fast can it get with an SLI setup.

As expected, the drivers aren’t quite ready for SLI. Games like ET: Quake Wars and Half Life 2 Episode 2 perform worse in an SLI setup on the GTX 280 than with a single card.
Conclusion- At the moment, a single GTX 280 is a much better option that two. With driver optimizations, this could change but certainly not for now.
