Choosing which GPU to buy

[Halken]

Okay, so what does the LTT community think is the smarter option?

 

Not sure if it matters, but I'm in Australia, my motherboard is an ASRock X670E Taichi Carrara, the CPU is an AMD Ryzeb 9 7950X, and the build (incl GPU + CPU) is EKBW watercooled config {https://linustechtips.com/topic/1458243-oh-baby-this-deskpc-is-coming-along-nicely-slowly/}.

 

 

So the question is, for the GPU should I stick with the originally planned AMD Radeon RX 7900 XTX, [downsides include, stock-levels & limited EBWK waterblock options]; OR should I instead purchase the NIVIDIA GeForce RTX 4090 [downsides include, Nivida, My PSU is a 850W so this may not be enough, price ~$300 more]?

 

Happy to have an open discussion, and the build is in no immediate rush so I am happy to wait a few months if required, however, if the smarter option would be to just purchase the 4090 now, then I'll do that instead.

The Price is a little above your budget but its a good bank for your buck!

I am vey new to this pc building thing so it may not work with your motherboard

Their budget isn’t 300, that’s the price difference between the two flagship gpus.

 

I would go for the 4090 and new psu if you want the best of the best. Yeah nvidia sucks and all but 4090 is the best money can buy if that’s what you’re looking for. Either option is plenty of power though.

Looks like the 4090 is a decent chunk faster, if the $300 more isn't an issue I'd go for that. Though you likely would want a higher wattage unit, IIRC power virus loads (like Furmark) can get the 4090 to chug nigh on 600W. Amazon's New World title famously killed a 3090 or two by accidentally running a power virus workload, so I would want the power headroom in case you run across a similar software oopsie. If you're sure you'll avoid that, or don't mind the system cutting off if it trips power protections, then 850W should be fine.

All I am going to say regarding the "eww nvidia" sentiment is look at how AMD is handling this 110 degree hotspot fiasco. Lets be real, both companies do shady stuff....a lot.

Whist I agree with the comments highlighting my PSU potentially causing issues, my (dumb face) self kind of designed everything fitting around that size (or similar) PSU (100x125x63.5)... as you can see from the link posted in the original comment, the layout/design would be a hard workaround.

If you can fit SFX-L, and it's available in Australia, Silverstone makes a 1000W unit: https://www.silverstonetek.com/en/product/info/power-supplies/SX1000Platinum/. It is $289 USD here though, eye watering price for that wattage.
