First of all, if you have just one dual GPU card, do you have to enable SLI\CrossFire in order for them to work correctly or does it act as a single processor?

Pending the answer to that and speaking entirely hypothetically (and assuming you could find a power supply powerful enough to run them), would running 4 Titan-Zs or 4 R9 295X2s in SLI\CrossFire be equivalent to 8-way SLI\CrossFire?

I know it's completely overkill but I'm just curious to see if it's actually possible.

Thanks.

The two processors work together via SLI and Crossfire. One Titan Z is 2-way SLI, while two would be 4-way SLI, and it is the same with the r9 295x2.

SLI is limited to 4-way SLI, so no, you couldn't use four Titan Z's. And even if you could, you would be limited to x4 with a 40 lane PCI-E processor.
