Actually all the screens ive posted have HT on, I turned it off to see if it made any difference while testing yesterday. All Ive noticed is that with HT on it runs a tiny bit hotter.
I also find it kinda weird that the GFLOPS in Intel Burn Test are actually about 15% higher with HT off vs On.
I've noticed around the forums some gamers turn HT off but other ppl with video tasks use HT all the time. Can't pin down any links but over at OCN there are some.
Just an observation .
