You know he uses ThinkorSwim every day! No gaming done here all business apps and internet.
That was meant more for other folks - not the OP. I have ThinkOrSwim's thinkDesktop (the paperMoney version) installed here, and I certainly can see why the triple-monitor play would be of use to a trader (even though I use it with just one display - due to lack of space for additional displays).
The other reason I would prefer the HD6670 is that (unlike most other Eyefinity-supporting cards) it doesn't require anything more than what comes through the PCIe bus power-wise - even better, it only takes up *one slot*.
