IMO, yes. 700 will not require any extra voltage. Have you ever used MSI afterburner or Nvidia's performance tab in their control panel add on to overclock before ?
I have an OC'd 9800GT in my other computer. I used the EVGA tool that came with it. My 470 is a Zotac ( I wanted EVGA again, but I got the zotac for $285 and I just couldn't pass that up). Will MSI afterburner work fine with my Zotac card?
I'm sorry, I'm a bit uneducated on OC'ing. That's why I'm here
*oh I also used rivatuner to OC my old 8600gt.
