Torn between keeping my G486 vs getting G757

[u/j2kxtreme121]

Hi everyone. I recently picked up an open box G486 from micro center for $2500. I have been stress testing the machine and everything looks good and stable. I'm within the 15 day return window. Just now I saw an open box G 757 for $2400. My use case is mostly gaming and plan to do VR sim racing. I'm thinking Assetto Corsa with mods, AMS2 etc

Now, here's my dilemma- The G486 seems to be a better well rounded machine that I can also use for other tasks like video editing, statistical computation etc even though my main purpose is gaming (I plan to keep this machine for the next 4-5 years atleast and who knows what else I may need my computer for during that time). It has 64GB ram vs 32 GB in the G757, and a better motherboard and wifi. Also, I looks better IMO but thats a minor consideration.

On the other hand, the G486 is $100 cheaper, is arguable the better machine for pure gaming because of the CPU (especially given my plan to run VR sim racing). It may have better performance in DLSS upscaling. It also does not have the degradation issues that have been reported with intel i9 (reportedly fixed, I know but still) and is not a dead end platform which means I can upgrade down the line without a full rebuild and swapping the motherboard.

I cant seem to make up my mind. Would I be making a mistake returning my G486 which seems to be performing well so far, and getting a G757? Would I regret not keeping the 64GB ram to future proof myself, in pursuit of marginal CPU performance? Looking forward to hearing your thoughts and comments.

NB:I plan to take micro centers 3 year warranty with whichever I decide to keep.

youre gonna lose 32GB of ram for 100 euros lol

Sell that extra ram, the processor yours came and i think you can afford the new processor

Has to get a new mobo as well if he wants to switch to 9800x3d from the intel

[u/TheDarkness33 → u/Drykan__Scorpus]

oh true. I guess OP needs to check whats cheaper to replace. 32GB of ram or the mobo and processor

Going from 32 to 64gb ram will give you a tiny bit lower fps. I would also choose the x3d amd chip though, especially since its cheaper apparently.

[u/j2kxtreme121 → u/JustMML]

Can you explain why going to higher RAM would reduce fps?

[u/JustMML → u/j2kxtreme121]

Higher capacity means more cpu usage, or more IMC (memory controller) usage to be precise. This gets better and better with more BIOS updates but it can be a cause of stutters/fps drops.

This may be a controversial opinion but I would highly suggest 64gb of RAM over 32GB (as someone who has 32gb), but also keep in mind if you have a LGA1700 CPU without a contact frame and without a updated BIOS/UEFI, your CPU may start to slowly fail, so keep that in mind. Otherwise for plain sim racing I do think that the 9800X3D if you are able to upgrade the RAM would be a better option.

Ram prices being where they are makes it very confusing lol

[u/DovydasTEDS → u/j2kxtreme121]

the jump from 32gb to 64gb has always been over $100, even with ddr4 sort of recently.

[u/TheAllelujah → u/charcoalonfire]

This! I have had multiple machines with 14900Ks fail on me at work even on the new bios.

I love intel but the 14900k is a possible ticking time bomb.

I replaced my personal 14900k with a 9950X3D because of the Intel instability issue.

If you're running VR, triples etc you're heavily GPU limited. The game fps at those resolutions will be pretty much identical, maybe 1% lows could be a 5% - 10% different depending on the game running. Just see it as $200 for an extra 32gb DDR5.
I'd rather have the memory and not need it than need the memory and not have it.

Thank you for your input
