Would most people go for P45 over X38 or even X48? I'm just thinking is the X series that much better now the P45 has ICH10/R?
bet it'd take a while to get all that metal off!
965 -> p35 -> p45
975 -> x38 -> x48
That's the upgrade path, with the 1st line being the cut down versions of the 2nd line.
as it most likely will be a common PWM design across most of their P5Q boards this may be a bit of an answer:do we really need 16 phase PWM?
& does it really run 16 phase all the time or drop down to e.g. 8 except under certain conditions?
975X doesn't reach the same high fsb as 965/P35 etc. (typically middle 400s with a C2D & mid 300s with a Quad) but it's a faster chipset clock for clock e.g. if you had a 965 & a 975X both running an E6400 @ 8x425 the 975X would give better results.Without being a pedant wasn't 975 just the poor prelude to 965? I'm sure i remember 975 being generally quite a bad clocker without many "premium" boards availible, whereas 965 was a beast with lots of "premium" boards.
While the heatpipe array remains very low profile to distribute the heat evenly – the north bridge and one of the PWM heatsinks are independently removable so you can use whatever cooler you want. This gets them around the heatpipe and watercooling limitation where people want to use their own.
