French site that pits the X1900XTX and SLI'd 7800GTs against ech other. I also included Techreports results when they tested the same games ,at the same res and, same AA settings. There were a few more games they tested but I chose the most popular. The chart shows the % increase of the XTX over the SLI 7800GTs.

The XTX doesn't come off looking so bad. I'm not sure why the Quake 4 results are so different, maybe they used HQ AF on the ATI or something (if someone can read French than maybe we can figure out why). The X1900XT is within a few % of the XTX so the arguement about it costing more than two 7800GTs just got sunk too.
If you couple the above performance along with the other reasons I mentioned in my first post (listed below) than I don't see a compelling reason to go with SLI'd 7800GTs over the X1900XT/X. Everyone's entitled to his/her opinion of course but hopefully they can back it up too.
1) IQ enhancements
2) ease of working with a single card vs. two (i.e. space and heat)
3) ability to overclock without resorting to voltmods
4) no profiles (they work pretty well but there are still bugs)
5) no tearing on an LCD (that is extremely annoying)
6) ultimate overclocking ability for the cpu (i.e. high HTT) is somewhat hindered by the extra overhead of SLI through the chipset, according to some.
