X5470 is much better for overclocking than X5492. Its multiplier is 10x with stock FSB333, while X5492 comes with 8x multiplier and stock FSB400. To overclock X5470, just find a motherboard with FSB400 support (such as Asus P5Q-E or any other P45 based board), install a high-quality cooling solution, set FSB to 400 and you have a 4.0 GHz Xeon. I've managed to overclock this CPU to 4.6 GHz with P5Q-E and DDR2-1066 RAM; while it is stable, it generates lots of heat and associated cooling noise.
