The Core i5 750 is a faster processor than the X4 965 but
TBH it really depends what applications you are running!!
Most games are not CPU limited unless you are using Crossfire or SLI setups with very high end graphics cards. A processor like an X3 720 will be fast enough for most games using a single card setup
IMHO.
Also unlike the socket 1366 motherboards or the AM2+ or AM3 based motherboards the socket 1156 platform is limited to Crossfire or SLI at PCI-E 2.0 8X.
Unless you are going for a Crossfire motherboard the AMD motherboards tend to be much cheaper AM3 than socket 1156 motherboards too.
If you are not overclocking a Phenom II quad core this motherboard is very good for the money:
