hey. i was thinking about upgrading my CPu some time soon. at the moment i have an athlon x4 760k Oced to 4.5ghz which is doing just fine. however i feel as if with next gen games coming out it may struggle a little in games with the r9 270x i plan to get this christmas. i will probably have to wait a while as after i buy the GPu ( which is probably the right choice as gaming is mainly GPu ) i will have to save up again. i was thinking an FX-8320 and a MSI 990Fx-GD65 for AM3+. if i do this will i need to buy windows again also? i have OEm widnows in my PC at the moment and i heard changing the mainboard makes it so windows no longer works and needs to be reinstalled. anyways, thanks for the help to anyone who answers this
