It's my mobo. The P5K premium. It does 16x/4x on the pci-e in crossfire to little or no gain. Lots of threads about it elsewhere. The 4x lanes on the second slot tank everything.

Sigh, premium my ass.

I've been down that road, and it's a pretty crappy one. The P45's x8/x8 is much better.

Ok, so one question, did you ever have any other ATi driver installed? this can happen when windows detects the card, and installs the latest driver as identified by windows update as being valid...which means each card may be running on a different driver.

Remove your current driver, and when it asks to reboot, say no, go to device manager and remove the vgas from there as well, deleting the driver. upon reboot, windows should install default vga driver, then you can isntall catalyst software.

Did all that plus tried a fresh install on an unused partition. It was working, just ran like crap. I had Everest showing both gpu temps, clocks and workloads in my g15 lcd.

Yeah, then 16x4 pci-e 1.1 is probably limiting you.

You found the culprit.

Time for a new mobo

Yah, there's even some articles about this with benchmarks to prove it. Good thing Far cry 2 runs like a dream on my single 4850. I hope Fallout 3 does as well. I don't want to buy a new mobo now, i7 is just around the corner. There will be mobo's supporting both Xfire and SLi.

Please don't spread rampant rumors. Vista and XP are all but neck and neck for performance.

I must admit....I am awefully tempted to install Vista so I can see how my gmaes perform on my Rig with DX10....really tempting indeed, just hate the thought of all those "installs" n "updates"...ugghh!
