Graphics Card Upgrade

[Carter St. Clair]

Budget (including currency): 1000-1600

Country: US

Games, programs or workloads that it will be used for: Mostly gaming, some AI and machine learning software/GROMACS protein simulations

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): 

 

Currently I have a 2070 super, ryzen 5900x, 4K monitor, 32 gb of 3600 DDR4, the NZXT H10 flow case, and an asus B550 gaming plus mobo

 

I was considering 2 cards to upgrade to from microcenter

 

Open box gigabyte 4090: $1485 (or $1650 new)

Gigabyte 4080: $1100

 

Which card would you recommend Should I consider buying the open box 4090 because of the large discount? Also, if the 4090, a couple a questions: would it fit in my case okay, do a need a 1000 watt psu (or 850 for the 4080), and would the 2 original case fans that came with the case be enough to support the GPU? 

 

LMK, thanks!!

Assuming the open box 4090 is in good condition its probably the better option. It will probably have a cpu bottleneck in games with either card though so I would look into upgrading that at some point. Unsure about the machine learning and simulation stuff.

 

A good 850w psu can handle a 4090 as long as you dont overclock it to its limits or upgrade to a super power hungry cpu. 1000w is a better option though if you dont already have an 850w unit as it gives headroom for those things.

 

What refresh rate is your 4k monitor?

Do you think I would have to worry about the card fitting or adding more fans to the case?

NZXT H10

do you mean the h510 flow?

if so then shorter cards like the MSI gaming X slim will be fine MSI GAMING X SLIM GeForce RTX 4090 24 GB Video Card (RTX 4090 GAMING X SLIM 24G) - PCPartPicker

But anything longer than ~332 mm most likely won't fit in the H510 flow with some fans at the front

It says this 3090 is 331mm

Sorry, 4090*

Exactly it fits perfectly with a fan in the front
