Currently I have an AMD Phenom II X4 925 (OCed to 3.5 ghz), but I was wondering if it was time to upgrade to an i5-3570k CPU along with the ASRock Extreme4 Z77 mobo? Future games that I want to play on PC are the new Sim City, SC2: HOTS, and Tomb Raider. I'm thinking Sim City and SC2 will be quite CPU intensive and not sure if my aging Phenom II will be sufficient to run these on max settings. I don't mind waiting for the new 1150 socket motherboards and Intel Haswell chips if that's the better option. Thanks!
