dual core
Got maself the amd athlon x2 6400+ 3.2ghz black edition, i can say it could probably be critically acclaimed as THE hottest running dual, with 125w output as described in a few reviews, i can definately believe that, when playing with a full load of crysis (all high, 8xaa 1440x900 @ 20fps but no frame dragging)
it reaches around 65, then after about 2 hours of this, it reached 70 and i started getting serious frame dragging, its obviously the cpu that was overheating as my gfx card barely touched 60 degrees, normally idling at 50c
so lets have a look at the deal on ocuk, for the 2.70ghz black edition, if i overclocked that, id probably get the same output, use less cooling and be able to play crysis a lot longer before problems occur? (if at all, but maybe with my little 8800gt i shouldnt be adventurous with anti aliasing and gfx on the elusive crysis!)
so this is one story of why you should choose energy efficiency over anything else!
*edit* i bought my pc last january and did not know much about pc's compared to what i do now, the company did not state that the black edition was mainly used for extreme overclocking, therefore i ended up with a stock amd cooler that id paid extra for without knowing (very bad service) had constant problems with overheating, ram getting fried, mobo blew at one point, kept sending them all the broken parts though and they did replace them, all but my psu, which was lucky as i found ocuk just prior to it blowing, bout a new one from here and ive pretty much been replacing the old parts with ocuk items ever since, the reason black editions are sold without a heatsink is they are intended to be used with a tough heatsink that costs more then standard stock fans, and are meant for serious overclockers, being the noob i was with no guidance, i just bought it because it looked nice, its a decent piece of kit but i would be better off with a 3.0ghz or less overclocked to the same 3.2 offered here.
