Performance worse after significant GPU upgrade - 4080 super

[ED209]

GPU is mounted vertically, it wont fit in the case otherwise. All cables seem to be seated correctly but i'll pull everything out later and start again.

As mentioned above, the first thing I would try is removing the riser and see if you still have issues. The riser may have been ok with your previous card but the new 1 may not be playing ball with it very well.

How comes it will not fit in the case, fans in the way?

Maybe a pain but it you cannot test with it all in the case as you able to build it outside the case without the riser?

The more you can strip back the better chance of isolating the issue. As above it needs to be tested without the riser. If it's still problematic after testing, is your dp/hdmi cable up to spec for the card?

The riser is brand new and came with the case. The case seems to be designed to only mount cards vertically but i'll remove the side and mount the card normally to at least rule that out.

I'll try swapping out the cable too although nearly sure its a brand new one that came with the monitor so im assuming it should be good, i'll still swap it out later.
