I have an Acer T180 with an Amd Athlon x2 3600+ (AM2+ scoket), Running windows vista 32-bit with 3gb of ram, 500W PSU, and Geforce GTX 650ti graphics (added a few weeks ago, uncles old card). I'm wondering what a good cpu I can upgrade too is, as I use this computer for playing games like minecraft, world of warcraft, warframe, starcraft 2, and Team Fortress 2 (on pretty low settings, and only gaming at 1440x900 resolution) But the current processor cant handle the games like warframe and tf2 very well, which is why I want to upgrade it. I'd prefer not to have to do a bios update, but I will if I have to, So can someone suggest a good cpu for me to upgrade to?
