Quote - Something else to consider if you're going "homebuilt"--the stock heatsink/fan that ship with the processor just don't cut it for stuff like Poser--I recently built an second generation i5, and running all four cores @100% for 30 minutes doing an HQ render meant that I saw CPU temps in the 95C range, which is way too hot.  Tossed an aftermarket cooler (which includes a radiator as big as my hand) on it, and I rarely see the temp get to 65C

Another option is sealed water cooling rig: it's not one that you assemble yourself but one with the coolant already in it and sealed at the factory (you replace the cooler on the chip and the rear case fan). I had one put in mine when it was built and my CPU doesn't get over 30-35C degrees even with all six cores going hard.
