alexsat :
and between 845 and 860k? what would be your choice?
The ZEN chips aren't going to be cheap.. they may come up with reduced models later on but for the price of one of these Athlon X4's at around $70.00 it's hardly worth waiting.
The 845 is locked so if you want to overclock the 860K is the best performer (after the 880k) on the benchmark charts, so it's well worth the extra $5.00 if you can't find it cheaper.
