SLI vs. Crossfire
GamePC has posted a very interesting article which compares the performance of X1900XTX cards in Crossfire against GeForce 7800 GTX 512MB cards in SLI. Beyond stock reference speeds, the editor also overclocks each setup to see which vendor offers the ultimate in stability and performance. Those assuming the test is a landslide victory for ATI's new GPU will be in for a shock to say the least.
Which is why, in the end, if given the option, we would still choose two GeForce 7800 GTX 512 MB cards in an SLI configuration in comparison to two Radeon X1900 XT 512 Mb cards in a Crossfire configuration. ATI might have some performance benefits here or there, but nVidia's platform as a whole is much more solid at this point
