QOTW: What's the worst PC component you've ever bought?

[markzero]

The runner up is my Corsair K90 keyboard. I actually really like it, in par6ticular the 18-key side keypad wioth programmable keys which are a bioon. The proinl;em is that the keys are way too sensitive. After six years with it, and even if I really pay attention tyo what I'm typing, I have to edit something practically every time that I type. I didn't this time, so you can see what I mean. I think my next keyboard needs to be a standard mechanical with heavier, more clicky, keys and I'll get a separate numpad and find a way to make it programmabnle.

The K90 is (mostly) Cherry MX Red switches, so you've got switches with lower actuation force and they're linear, no bump when you press them. (My old K60 is the same way.) So try to actually test ones at stores that either require more force or have the bump, or even both. If you Google Cherry MX switch comparison there's a bunch of guides to help you out, and a lot of them also compare to non-Cherry equivalents.

I bought an Nvidia Physics Card, it never added up to nothing. Once I got it and showed all my friends than put it in my first water cooled Koolance case with a 6800 nvidia gpu almost nothing showed any real difference. I should have been reimbursed for the "Physics Card" !!
