Some testing I did to answer my question of which setup should be in the FSX rig - i3-540 @ 4140mhz or a stock i5-3470. (X-posted from my thread) The i5-3470 + B75 mobo + 16gb RAM was about CA$350 with taxes and shipping (about $310 sans taxes/s&h). The lowest for a K-series CPU in Canada? There was a deal for a 3570k + mobo for $299+tax so $50 for RAM = $350+HST = $395-ish. For an FSX specific build, K series all the way but I thought this would be useful to see some "regular" hardware in action.
