read both the threads on this, and they're both an interesting flame-fest
and after reading the threads, i've still decided that an 805 is the better option for me, while i put my sempron 2800+(754) into retirement as a file-server(it'll run at stock speeds on less than 1.2volts )
why? cheap Dual core - in order for me to get the same in amd, i'd have to get an X2 3800... ok, it'd perform better, run cooler, and(a bloody stupid statement) be cheaper to run than the PD, the pure VALUE of the purchase is much better...
i'm getting a PD 805 for $210 australian, about $150 US, and can get a gig of ddr2 for $90 aus, about 65-70 USD...
bundle in a decent motherboard, in this case a Asus P5ND2-SLI, for $170AU - 130USD, and i've got the guts of a new system for $470 australian, or about $350 american...
the cheapest i could do with AMD, was about $20 more, and that was using a athlon64 3200+, in socket 754....
so now, take your pick between those two, a 3200+, which i might be able to clock to what, 2.4-2.6? or a PD805, which should be easier to overclock, as it wont even be looking at coming close to the 800MHz fsb (infact 1066MHz on that p5nd2-sli) the motherboard would use..
heat? cost of power? come now, where i am in australia, its never hotter than 30 degrees C in summer anyway, and power is fairly cheap, at 14c/KW(10.5c US) at the highest peak time/price, so that kinda throws that argument out the window. even moreso that i'll be considering my next upgrade to happen within about a year or so anyway - with AM2 and conroe coming out, you'd be crazy to do any big upgrades right about now, in my opinion
