Like the title says, I have a max budget of 500 dollars and I don't know if I should buy an I5 processor with a Z97 motherboard or buy a R9 280x by XFX. I can't buy both because I need a new power supply if I buy the graphics card and I do need a few more case fans. My current CPU is the AMD Athlon 860k overclocked to 4.4 Ghz. The games I would like to play are Battlefield 4, Black Ops 3 and maybe a few other FPS games at 1600 x 900 resolution. Any advice would be appreciated thanks.
