Now the real question on the Maingear end would be.. E8400 Overclocked to 4.0 or the QX9650 overclocked to 4.0![]()
if you can afford it, go the 9650. if the cores are clocked the same, even if your apps/games can't use all four cores you will still see the same performance levels as the 8400.
if your apps do use all four cores it will beat the dual core hands down.
