You guys should check out Pale Moon/64 (Windows optimized version of Firefox).. It ran great on Win7, apart from the fact, that the initial load of the browser was a bit slow. But on Win8 it even loads fast and it is blazing fast and uses less ram than on 7 (I know because on one of the million and one extensions), even though I restored my old profile with 29 cookie blocking, https finding extensions.
I haven't tried Opera64 yet, but I will check that out. IE10 is fine, but I guess once you get used to the massive amount of extensions, it is hard to settle for less.. I ditched Chrome a while ago. It doesn't feel as fast, as it used to do, but more importantly I just felt like the entire browser was one giant key logger, and frankly I'm not comfortable with Google Brother watching my every move.. Some times I use Chromium for development though..
