I
did see the benchies.
In most cases mid-range conroes beat AMDs FX-62 without overclocking, crossfire setups should see significant gains. And considering the chip is cheaper than AMD64 X2s AND a far better all round performer, AND looks promising to be an excellent overclocker, the only reason not to get one is not being in the market for a system rebuild, or a false sense of loyalty.
However, there's no doubt your current system is more than adiquate for the time being. But for those who are looking to build a new system, it's pretty clear which you'd go for.
