Considering how many times I've had to tear down my loop just to upgrade a video card or something of that nature over the years, I really should have invested in QDCs. Do you find that they work generally OK?I always put QDCs on my gpu for this reason. It makes working on them easy, well easy enough. You're more likely to pull the gpus than the cpu in general use. Also, I'm not big on assembly with the card in the slot and you're more likely to fubar something with such little room to work with.
