X1800 Crossfire performance bump on RD580?

[SuperU21]

I'm having a few issues with my A8R-MVP motherboard and Asus Tech Support has been a nightmare. I'm planning on ditching this board for another. I still have my X1800XT and wonder if perhaps the newer boards that support 32 lanes will give the X1800 crossfire a boost or if its not even worth it.

I'm at a position where I can go get the new board and crossfire 1800 and call it a day or go get an A8N32 and wait for the new Nvidia cards to come out and jump ship to Nvidia when they release a new one. But if the performance of the 1800 crossfire goes up a bit from the board alone I'd be for it.

So I guess the question is, does anyone think the X1800 Crossfire setup will get a bump from the 32 lanes? Have Nvidia cards seen an improvement from the increase in bandwidth?

Word on the street is that it will indeed increase performance but, by how much, is yet to be seen.

According to this:

The improvement on full dual 16x is nada for NVIDIA, I doubt it would be different for ATI. The cards don't need the bandwidth, maybe next gen will see the need.

X850 crossfire setups using advanced AA options would probably see a performance boost.

The only reason right now to have 2x16PCI-E lanes is for quad sli.

AGP is just now starting to max out at 8x, there is really no boost from using an PCI-E over AGP atm though, I believe when the new gen of games (mainly DX10 games), AGP will be put in the pasture and sentenced to a life of rejection (just like PCI is now).
