It's an excellent mobo for a 6600 being one of the top overclocking 975s.
In fact it's in short supply due to terrific demand & there has been some price-gouging going on.
It officially supports Crossfire & you can unofficially run SLI with hacked drivers (the bundle even includes an SLI bridge).
I would say its the best 975X mobo for OCing, even that not most practical since it has only got one PCI slot. The Foxconn 975X7AB performs just below it and has more accesible PCI slots.
Neither of them need to be highly cooled on the Northbridge or modded to reach some 450+Mhz FSB.
or does the abit still sound better......because the abit doesnt come with audio and it also is stumping me on how i am going to fit 2 graphics cards in there and a pci sound card in there at the same time.......the heat fans on the gpu will block it..... and also the abit is expensive!!!
The 'sound card' on the abit is simply the audio codec on a separate piece of PCB, this is said to reduce the eletric noise made by everything else in the mainboard, DFIs Karjan audio modules work this way too.
Its hard and complicated to OC on the Asus P5W DH, the Foxconn 975X7AB is a beter choice for the average Joe.
