I'm looking at new motherboards to go with my new build I will soon start getting. The question I have is if I should go with a board that only supports CrossfireX or Hybrid CrossfireX instead. Only issue is all the boards I see with CrossfireX Hybrid run at PCI-e x8 when dualed together, but run at x16 when only a single card is active. The CrossfireX boards I have seen run at full x16 when in dual setup. Is there better benchmark results from CrossfireX or Hybrid?
Just out of curiousity too, will a 2.1Gen graphics card work on a 2.0gen PCI-e slot?
Hybrid CrossFire is mostly for power savings and isn't recommended for gaming,in hybird Crossfire you can use a low/high end card with the motherboard's integrated card which gives you a little boost in gaming.
But Normal CrossFire is when you use 2 more powerful cards and that's recommended for gaming.
And yes a 2.1 Gen card(i suppose you mean HD 5970) will work on a PCI-E 2.0/1.0 slot
