yeah agree with all the above post. go with core 2 duo e6300, it's the most value budget cpu to get.
i have used e6300 and e6600 and for general application you can't tell the difference. of course the e6600 would go faster but for the price, e6300 looks pretty interesting. in average e6300 would be only left around 20-25% behind than the athlon fx-62, so it's a very very very good cpu for the money.
