I've bought used CPUs before and never got a bad one, but they have always been for older laptops to upgrade. I figured that if they lasted long enough to be labeled "used" they probably wouldn't die on me. Insert your experience here. I'm wondering if it's a good idea to buy a used 4690k. I've always thought that CPUs were probably the least likely part to stop working maybe next to RAM. I generally don't buy used components like GPU or hard drive because the price cut isn't worth the loss of warranty, but I'm wondering if a 4690K is a good gamble or not. Anyone with experience in this kind of thing? Opinions only need not apply.
