I have an HP Pavilion a6000 and I want it to run games without the lag and choppiness. Any suggestions?
You won't be able to run any recent games on the HP Pavilion a6000. You'd have to replace the motherboard, RAM, CPU, GPU, case, power supply. You can probably keep the hard drive, though.
I'd suggest starting with an R3 1200/ G4560 for the CPU. If you choose the R3 1200, then you'll need an A320 or B350 motherboard. If you choose the G4560, then you'll need a B250 motherboard. Find 8 GB DDR4 RAM, a bronze rated 400-500 W power supply, and optionally a dedicated graphics card. One thing to keep in mind is that the G4560 has an integrated GPU, which might even be enough depending on the games that you want to play.
