Hey guys,
I bought a new gaming setup a couple months back, 7970, 120Hz monitor, the usual. The monitor I have only has a dual link DVI port to run at 120Hz and due to my lack of thorough research I bought the MSI 7970 Lightning BE which comes with 4 mini DP and 2 single link DVI ports. The only way to achieve 120Hz with the 7970 would be to buy a ~$120 adapter (Located in Australia).

Now to my question. If I was to crossfire my 7970 with a 7950 (~$210 minus the adapter cost) would the 7970 still work at full effect, considering I would need to plug the 7950 into the PCIe 3.0 slot as the DVI from the monitor would need to plug into its DL DVI port?

I know hybrid crossfire'd cards have been able to run at their own specs for a while now, I am just uncertain as the more powerful card, 7970, will not be in the PCIe 3 slot and not connected to the monitor.

Cheers Luke.

I was planning to crossfire, hence the 850w PSU I bought as well :) If I need to buy an adapter for $120 I may as well crossfire now if it saves me the money. That is if the configuration I want is worth it, otherwise selling it might be better.

The best option may just be to sell it then and buy a new card then to avoid the hassle. Then later on crossfire the matching cards. Any idea how much a used 7970 Lightning BE would be worth?
