Is my setup better than say a 965 setup for like 785 shipped?
A 965 setup uses the AM3 socket which has more longevity. The i5-750 is a faster processor overall, but the 965 is a better value considering the motherboards are cheaper and the processor is cheaper.
The i5-750 is 200 bucks, and for 9 bucks more you could get a Hexa-Core AMD processor here :http://www.newegg.com/Product/Product.aspx?Item=N82E16819103851&cm_re=hexa_core_amd-_-19-103-851-_-Product
And just get it with a motherboard combo.
The Hexa-core will outdo the i5-750 in multitasking and gaming. It has turbo-core tech which overclocks up to 3 cores if the other 3 are not in use. This happens alot in gaming, so its designed to improve gaming performance.
