I have been having some issues with my computer slowing down so i'm thinking its time to upgrade some hardware. I currently have an Asus M5A97 MB, FX-4100 CPU, with GTX 660ti GPU. I believe my graphics card will have to do for now because i don't believe my CPU can handle much more, so i'm looking to upgrade MB and CPU and need some input on which way to go. I don't really have a preference towards AMD or Intel so i'm open to all suggestions that will give me the best performance for under $500. Thank you in advance for all your help.
