Could that have something to do with your motherboard? I plan on
getting Gigabyte GA-P35-DQ6, will likely order all the parts this
Monday or Tuesday. My choice is still between those two CPUs even if
FreeBSD has some issues with them right now. Hopefully it will be
fixed before 7-RELEASE is made.
I could still use some advice on which CPU would be better assuming
everything works as it should. I'm leaning more towards Q6600, since I
could overclock it a bit and essentially get 2 extra cores for free.
The main question is still whether ULE will take full advantage of the
available processing power and offset the negative impact of lower
On Windows tests it's pretty clear that things like video editing and
3D rendering greatly benefit from four cores, but of course it's
difficult to locate similar tests run on other operating systems.
