Is Crossfire at 16x-4x bad??

Hi everyone

I want to add another AMD 6870 to my computer setup but the problem is my ASrock 970 Extreme3 only supports 16x/4x in crossfire. Will this totally kill the point of getting a dual 6870 rig? Will I notice the performance decrease at all? Also buying a new motherboard is not an option ; I like my ASrock it has served me well and I don't want to upgrade if its necessary.
Or is Xfire even necessary at the resolution and games I play??

Thanks everyone

Games I play
ME 1,2 and 3
Battlefield 3
Crysis 1 and 2
Skyrim
Metro 2033
League of legends

  1. Not good my friend, not good. 16 and 8 would work but 16 and 4 is a big no no. You can use 4 for a soundcard or sata card
  2. x4 is definitely going to handicap that card.
  3. You can probably sell your 6870 and get 560Ti($190) which has slightly better performance

    or sell 6870 add your savings and get 7850=6950 performance(~$250)

    so crossfire is a no...why would ASrock even bother advertising it then. Kinda disappointed I even got the mobo... hmm well is the 7850 going to be that much better then the 6870?? I always thought the 6950 was a waste because there was like a 5fps difference. Would the 560ti be worth it? or should I get a 570?? I want a least something comparable to 2x 6870's or 2x 6850's

    thanks

    560ti is a bit slower than a 6950 but remember you could always buy a dual GPU card. PS a GTX 570 is nowhere near the performance of 6870CF or even 6850CF OP what is you PSU and budget ?

    What dual GPU card would you recommended??
  6. Can anyone tell me how much performance loss would I actually receive if I crossfire a 6870 in 16x/4x??
