I want to give you guys as much information so that you Can give me the best advice knowing exactly what I have. I checked my manual and below is the section about expansion slots. So if I can't use the very first one which one would be best to use if need be you can scroll up and refer to my diagram of my motherboard but I think this should also explain it very well. I guess I will have to figure out if I do use one of the slots how to enable it. Maybe I should start a thread in the motherboard section asking that specific question?? What you think
I know why you asked whether it fits, its because you have a very unusual GPU right now with a *massive* heatsink hanging over the top of it. That isn't normal. Regular GPUs always 'start' at the top of the PCIe bay they use (where it sticks out the back of your PC), add maybe 3-5mm for a backplate on top, and the heatsink hangs underneath, not on top of it.
One notable bit here still is the so called sagging of the GPU. Visually inspect your PCIe slot because that card has been hanging there for quite a while. Check for dust and blow it out, and see if the slot is still intact and 'straight'. If its bent, use one of the slots below it. Better to do that before something says zap, because why not, if the slot is at least x8 you won't ever notice.
