Re: intel e6300 or amd x2 4200+?
definitely go with the E6300 it will blow the 4200 X2 out of the water! and the price is also pretty reasonable too. Those core 2 duos are very easily overclocked and the benchmarks are amazing on those things.
Desktop: Dell Dimension E510, 2.5GB RAM, Intel P4 3.0GHZ, 250GB HDD, Windows Vista Premium. Might not be the best, but the old girl is still running good.
