I want to upgrade from Athlon II x4 630(atm at 3.2 Ghz from stock 2.8) and crap mobo MSI 770-C45 to Intel G3258 and Asus Z87-A,GPU I use is Sapphire R7 260x OC 2gb with 4 GB ram 1333Mhz 2x2 Kit.Will I see huge improvement with this CPU(will OC it)?.Later when i get more €€ i will probably get i5 4th gen if price drops when Broadwell gets out.I'm really desperate what to do here.I'm doing right move or to stay on this crap build and get more money and buy all at once or go step by step and see how will it go.In my opinion i think G3258 even OC to 4-4.2 GHz will blow away this AMD I own and that I will see huge improvement.So please help me out here.I really appreciate any help you can provide.
