And you can't horizontal span with DX 10? WoW is not a DX 10 program.....

Let me test with my 8800s (DX10 cards) real fast.

Edit: Hmm.... seems the Nvidia control panel is all new and I didn't see any options for clone, dual view etc.

But the 8800 is known to be fairly buggy when it comes to features (I can't even turn on SLI because I have 3 cards plugged in, even if one is completely disabled). Can anybody else confirm? That seems awfully dumb.
