To not expect anything to run on that setup. The gtx1070 was a phenomenal card back in the day and I’m sure it can handle a lot of newer games still.

This is not true. Until a couple of months ago, I ran a 10 year old rig with a gtx960. It could handle Elden Ring to name one without problems.

I’m running a RTX4070 too and was advised to not hold back on PSU. I’ve completed the new built about 2 months ago and people warned me about PSU quality based on the one I had selected first. Better to invest a little more but have stable performance down the line.

NOTE: I’m also running a fairly power hungry CPU.

I ended up with a Corsair RM850x Shift. I did find installation quite a lot easier with the Shift version.
