Is there any major advantage in getting the 6300 because I'd rather save the money if the 4300 just/nearly as good
The 6000 series has total of 3 modules/6 integer cores instead of 2 modules/4 cores on the 4000 series. If the price is close, go 6300. Last I checked on newegg, the 6300 was only $10 more than the 4300 ($139 vs $129). Thats a no brainer. But if the gap is $30 or $40, then its a tougher call.
