Yup, the initial reviews are extremely impressive. They even use the ICH5/R so you get the onboard raid as opposed to their 875 board! I just don't get why Asus's board performs so much better than anyone else's. I'm glad I held off on my 875 purchase. Now I am going to give it a few weeks to see how some more reviews turn out and if some kind of explanation is given for huge performance difference between Asus and the others.
I'm getting my p4p800 soon, going from an abit bd7II raid. I currently have my 2.6C processor running in my BD7II 216mhz Abits been good to me, but I need the on board IDE Raid, plus the memory, cpu vcore, and agp have higher voltages then the ic7.
P4P800 is the 865i chipset. It doesn't have PAT or ECC but it has Asus' version of PAT (MAM, Memory Acceleration Mode) which gives it the speed boost it needs to compete with all the other 875i boards out there. It only runs in 1:1 mem config and it can be turned off thru the bios, unlike PAT on the 875i.
I was talking more about the variances of processors and memory that were used in the reviews. All the reviews and benchmarks I've seen were so close that no one would notice the difference. I'll take a mobo that's cheaper for that slim of a margin.
