Hi, I have just bought a new PC, it has two 3g Xeon duel core chips and hypo-threading with 2 gb DDR ram and an ATI 256 mb graphics card and it was taken twice as long to render as my old 3gb with 1 gb of sd ram and a 128 mb Nvider card. The more of the hypo-threading and duel cores we turn off the faster it renders. Can anybody tell me what going on and how I can improve things. Thanks Bill
