Hi everyone.

Here is the stats of my current PC:

AMD FX-6100 3.3 GHZ 6 Core CPU w/ stock cooler
AMD/ASUS HD 7770 OC 1GHZ 1GB DirectCU V2
12GB DDR3 RAM
MSI 760GM-P34 (FX) Mobo
500GB WD Drive
600W Ultra Power Supply

I'm being given another ASUS HD 7770 OC videocard from my friend. I want to Crossfire these, to get better performance in Battlefield 3, but I only have a PCI-E x16 and a PCI-E x1 slot.

I found this adapter online:

There is also a powered version, but I'm not sure if I'd need that as I have another GPU power adapter.

Could this adapter be used to Crossfire two AMD HD 7770 cards? I know I'd be limited to about 5GB bandwidth on the PCI-E x1, but it should give performance increase anyways...right?

My board supports "Hybrid CrossfireX", which allows the Onboard graphics chip (760g) to Crossfire with the discrete card (HD 7770).

How can I do that? Think it'd benefit me?

To get any benefit from that second card you will need to get a new motherboard. No adapter is going to get rid of the limitations of the board you have. On top of that Crossfireing two low end boards does not give much of a performance boost anyway.
