P45 Crossfire Performance

[Mungri]

Add to that less heat coz of the NB die shrink

Not necessarilly. MSI stated, I think on hexus, but not 100% sure where I read it, that the reason the P45 needed much better cooling was because it runs around 10 degrees hotter then the P45. I have had big doubts about the P45 which pushed me further to getting the X48.

Time will tell how well it does with overclocking, but as far as graphics are concerned, IMO by the time cards are so powerful that they actually need the bandwidth of PCI-E 2.0 16x/16x, we will already have PCI-E 3 released. An 8x/8x combination still provides all the bandwidth that current cards require. Its like how putting a 512 bit memory interface on ATI cards makes virtually no difference over 256 bit, also, a 500 Mhz ram overclock on my 3850's (I tested at 1600 and 2100 Mhz) only gives a difference of around 300 points in 3D mark 06, but GPU overclocks scale much more higher then the ram

Bandwidth is currently too far ahead and bottlenecked by current GPU's, and once we have faster cards in a few years time, the current bandwidth we have will be plenty for them lol.

Bandwidth = overrated. Its the same as the difference between DDR2 and DDR3 system memory in terms of performance.
