Not for the price its not.....its terrible
I honestly don't think it's that terrible. Please hear me out.
From my 4080 I will get double the frames and double the vram, basically a 100% uplift or near abouts. The 4080 had an msrp of 1200 USD. If I was coming from a 4090 id have second thoughts about it.
Unfortunately, this is the world we currently live in regards to prices. Yes, it's going to be scary what the release prices will be down under but hopefully I get a chance for the dust to settle on prices before there are any stock issues.
I originally went a 4080 coming from a 6800 XT. I paid 1749 AUD for the 4080 and the cheapest 4090 I could find was 2749. I said to myself I would save the 1k and put that towards the Nvidia 5 series or Radeon.
With the power supply, I believe I will get away with the one I have as I will be power limiting if for maximum efficiency:
20% Efficiency Boost by RTX 5090 Power Target Tweaking but I will be donking in a 1300w
I purchased ages ago on special just in case.
