Apparently, my CROSSFIRE is worse than a Single 4850, and Tomshardware's Crossfire is more than 2x the score.
TWO Crossfire HD4850's, linked together, (it worked when I installed them.)
Asus P5W DH Deluxe (In crossfire it's only 8x/8x, but that isn't why.)
E6600 Core2Duo OC'd to 3Ghz
Creative X-Fi Platinum Sound Card
Thermaltake Toughpower 750w PS
I've checked before, and ATI Control Panel seems to be setup correctly, and is said to be detecting the cards in Crossfire. But obviously something is wrong...
Toms was using a highly overclocked quadcore which gives you the best 3dmark score by far, which is one the reasons a 3dmark score has nothing to do with your actual in game performance. Your motherboard is also limiting your 4850s a bit with the X8/X8 bandwidth. All that said you need to try some serious overclocking because my cousin has a system with an E6750 @ 3.6 Ghz and 2 8800 GTS 512s that score 16000 in 3dmark06.
