My dad gave me an inspiron 660. the specs are Here (I did install a wd 160 gb hdd and an nvidia quadro nvs 290.) I am interested in upgrading to a gigabyte gtx 970 mini itx and a corsair cx650m power supply I wanted to know if the gpu would work with the psu, and if the gpu would work with the cpu without upgrading cpu to core i5 or i7.
