Question Help me pick the right graphics card ?

[bx88]

My budget is 300 dollars i have to go for used card to get better value
I have faced two cards
RTX 3070 TI 8GB Aorus Master 310 dollars
RX 6800 16GB Asrock Phantom Gaming 300 dollars
Which of them is best to get? the both are same condetion very good condetion and temp
My Specs:
I5 11400
Gigabyte b560m h
16GB 3200MHz
PSU: Bitfinx Formula 650w Gold

RTX 3070 Ti is a bit better,

However, since it's used RTX 30-series GPU, it most likely is ex-mining GPU and i would not buy it. Since it may die soon after. (Actually, same could be with RX 6800, since you never know with used GPUs.)

Oh, RTX 30-series has high transient power spikes and your 650W unit isn't enough for it. GPU alone is 290W and with transient power spikes, you're looking towards ~500W for GPU alone. So, better to get RX 6800 instead.

👍 Great quality PSU. Rare sight these days.
But PSU is bit old (came out in 2018) and now, is past it's warranty as well (it ever came with 5 year warranty).

PSU should be fine if you had it since it was brand new. But if you bought it used, then it's completely different ballpark.

I tend to agree with the above, in that if you don't want to replace PSU, go with the AMD variant. The extra VRAM is a nice to have. The choice is far easier if you don't care about ray tracing.

It may be worthwhile to consider a new CPU, but honestly think it would be better waited for a 'next update' cycle where you get something more modern. If someone gifts you an 11700 or K variant it wouldn't be a bad thing if mobo and power delivery support it.

formula is a great PSU , yes it is a bit older
but units like this can often deliver even more than their rated power (short term)
in fact this units OPP triggered at 850w in testing (so there is plenty of room) .

not counting the video card the rest of the system will not consume more than 150w of power ...
11400 will hardly ever hit 100w under normal conditions (gaming included) .
(when you are performing some stress tests sure it may exceed 100w in some scenarios but not while gaming) .

the highest measured power spikes i was able to find with rtx 3070Ti was around 420w .
even if it hits 500w for a fraction of a second it will still not be nearly enough to trigger
the psus opp protection causing it to shut down
(even if we factor in its age and slight degradation in performance) ...

that being said i would not recommend buying this GPU for a different reasons .
while it has enough raw power its 8gb of VRAM limits its capabilities to a degree .
for that reason i would rather try to find slightly slower 4060Ti with 16gb of VRAM
(in my country i was able to find it for 350 dollars in used condition - and there is always room to bargain)

however after a gpu upgrade you may find your processor to be a limiting factor in some games .
especially when it comes to 1% lows and overall smoothness of gameplay in cpu heavy titles/locations .
i was personaly testing games with 10400 (only sligtly slower cpu than 11400) and
compared it with 9700K and 5700x (using gtx 1080 back in the day)
and even with gtx 1080 the gaming experience was just better with 8 core cpus and higher clock speeds
(while the average FPS remained almost the same
i was experiencing far less FPS drops and micro stuttering ) .
intels older 6 cores with locked multiplier are just not too great for todays gaming ,
don´t get me wrong you can still game on it and be perfectly happy with it ,
its just if you tried i7k you would never go back to locked i5 ...
(however i would not recommend such an upgrade with your current motherboard)

Well, I just got the RTX 3070 TI. The card is in very good condition, never opened, and comes with its original box. The temperatures are excellent. I don't think there's a problem with this used card, as it's for personal use and not for mining.
I contacted the seller in my country, and they said I could return it and get an RX 6800.
Well, I first tested the card on Furmark to make sure there wasn't a problem with the PSU, and everything was fine. I don't think the PSU is a problem here.
But when I started trying out games like Marvel's Spider-Man 2, i faced a lot of stuttering and the Framtime isn't constant at all
i was play this game on my old card RX 5700 XT and was everything is fine
i really don't know the reason

i think the psu isn't problem here because it's a high quality.
the ray tracing is a good option to have i almost play a AAA games but how much rtx better than rx i watch a comparison between them and rtx was better in few games but most of them are same framerate
it's the raytracing looks better in RTX is that the reason ?

Thanks for your replying
i get rtx 3070 ti
i get the card and I'm pretty sure it's for personal use and not for mining.
