Hi everyone. I am currently finishing up a built computer and I would like a recommendation on what type of CPU to replace in the computer. My current CPU is 4 years old (AMD Phenom II) and I would like to upgrade to a good gaming CPU. My motherboard is an ASUS M5A97 EVO with 32 GB of installed RAM. I have a 450 watt power supply, which I was thinking may also need replaced. My computer lags terribly with these upgrades. Please give me your suggestions on what CPU to buy and why. Thank you for your help.
