well... an i7 I'm pretty sure though you shouldn't cause I don't think it can handle the thermal output very well.. Although depending on your chip set it's able to upgrade to a dual core or quad core i7 as it's the same TBD and the cooler is designed for it. I haven't looked or found any reviews and things they say it can't handle the thermals, I'm just speculating based on similar instances and knowing certain chip sets can only up grade till the thermal limit which I don't know for that one. I mean a i3 yeah but that's not much of an upgrade.
