While playing some demanding games on my 560ti my computer randomly shuts off, my guess is overheating? should i get a cooler for it? i took it out and cleaned it, but still does it, if i lower the graphic settings it will run it, but not when its on the optimized settings

Cpu i5-4670k
8gb ddr3
gigabyte z87-hd3 mobo

What's your PSU?
9 times out of 10 this is caused by your GPU drawing more amperage than your PSU's 12V rail can handle.

GPU's will always run pretty hot, so I can't determine that that's the problem.
Use a monitoring program such as Speedfan or Afterburner to check your temps while gaming.
If they're less than about 75-80C, that won't be your problem.

For your PSU, I'd try something like a Corsair TX600 or a TX750, those should supply more than enough amperage.

And yes, that CX600 should do fine, it spits out 46A on the 12V rail.

Use MSI Afterburner to monitor the GPU temperature and adjust fan settings accordingly. You can set a fan curve so that the fan speed will increase with temperature.

Do you know your CPU temperatures?
