if your only doing gaming and watching hd movies the 965 is a clear choice..if your doing video encoding,converting etc u shud get the 1055t
there is only a 1k price difference so i think you should take the 6-core..however it will be a bit difficult to overclok the proccy as compared to the 965..if u get a good mother board along with the 1055 it would be perfect, stay away from 890gpa-ud3h as it has a sucking bios..people at overclock.net have had numerous probs setting up samsung hdds,different rams, etc

i just read your first post,, sorry didnt read the "no overclocking" part
then the 1055t with msi 890gxm-g65 is perfect.. even i am buying that board
it has loads of features usb 3, sata 3, crossfire,sli,good layout, nice colour combination all for 7200
