Any thought??

Yeah, i want to Xfire too in future. The case i will have is excellent. A Fractal R4 Define. I can with adapter install a HDD in secon 5.25 bay, and install two SSDs (if i ever buy another) behin the motherboard.
With this i can remove the top and lower HDD cage, allowing for even better air flow to 2x R9 280X.

Epic case is epic biggrin.gif

You should note that those results are at full speed x16 in 3.0 and 2.0 for the sake of equal conditions.

TPU had a more exhaustive test with a GTX680 and a 7970 at all PCIE speeds

At 2.0 x4 there are some performance hits, some more severe than others, but it appears it mostly depends on how well optimised the game is, i.e BF3.

Thanks for the link nortrop,I get what you're trying to say..
So,in your opinion if i Xfire 2 gpus,one in a X16 slot and another in a X4 slot,
I will downgrade the "speed"of both gpus?Meaning that it would be better to have one gpu with better results or It will only affect benchmarks for some games?I'm kind of a noob,never had 2 gpus before:-D

Like I said, it all depends on the game. Some titles scale well in crossfire, others don't. At x16/x4 the overall performance would surely be less than that at x8/x8 or x16/x16. Whether it would be 1fps or 50fps it all depends on the game and driver support/optimisation.

Here is some more food for thought, despite the article being a bit dated it's a fair representation.

Your motherboard is not an optimal choice for crossfire. Even if it was, multi GPU poses more tradeoffs than benefits, compared to single GPU (more heat, noise, higher power consumption, microstutter, driver support...). If I was you I'd stick to a single top end card.

Edit

Initially I wanted to link this OCN user test, but couldn't find it, so here it is: Behemoth777's Crossfire x16,x4 vs x8,x8 Comparison
Quote:
Conclusion: If your looking to go crossfire, or even thinking about doing it in the future, make sure you go with a board that supports x8,x8 crossfire. It is a much better experience and also frees up your other pci-e slots for sound cards, raid cards, ssd's, etc.
