i have a dell inspiron 660 i5 3330 with everything on the inside stock except for a gtx 660 and a 500w coolermaster. i just bought a core 3770 i7 to replace the i5 (both lga1155) iv only ever replaced the psu and gfx and while doing research online i see stuff about Proprietary hardware.. what i want to know is, is this computer considered Proprietary? will i have any problems installing the i7?
