Torn (Thinking about biting the bullet and buying a pre-built) 30 series gpus

PITTCANNA
Visionary

So my b-day is in about a week.  I have plenty of funds to plop down some real money

Option a:

i9 10900KF 3.5GHz Processor; NVIDIA GeForce RTX 3080 10GB GDDR6; 32GB DDR4-3600 RAM; 1TB Solid State Drive

 

option b

 Intel Core i7 10th Gen 10700K 3.8GHz Processor; NVIDIA GeForce RTX 3090 24GB GDDR6; 16GB DDR4 RAM; 512GB Solid State Drive

 

I am leaning towards the 3080 just because i9 and 16 more ram.

 

or just wait off.

What is your current rig? I would have different advice if you are running a GTX 1080 versus an RTX 2080 TI.

i7 8700, 16GB, RTX 2080 TI, Rift CV1 | i5 4690K, 16GB, GTX 1660 TI, Rift CV1 | Quest | Quest 2

So i have fairly decent right now:
i7-9600K, 2080 super, 512 ssd, 16 gb ram ROG Motherboard.

I can some vr games on it with link but, i want to sim race in vr.

Hard to evaluate with no prices shown. Cpu matters very little, personally I'd go for the fastest gpu - even if the RTX 3090 seems fast, you can easily use all its power in current games like Furious Seas, Blair Witch, EverSlaught - and many other games when you start to increase res. 

A 3080 will probably bring you about 35% more fps, while 3090 should bring about 60% more fps. Based on OpenVR Benchmark results. 

 

You can always add more system ram and another SSD. 16GB are on the low side, but should not really be a problem. 

 

Unless the price difference is huge, I'd never go for a 3080 if you can get your hands on the king instead 😉 Try to ask if anyone in here would swap their 3090 for a 3080, even if you gave them 1k ... or 2k ... 🙂

So the 3090 pre built is 200 dollar more (3,000)

the 3080 one costs 2,800

Do you really think the processor won't bottle neck?

$200 more for a 3090 is a steal.

 

These are the cpu differences you may notice when turning up the eye candy:

I would gladly have kept my i7 7700K for the 3090, but the i9 10900K gives me some street credit from dudes not knowing better, lol. 

 

If you play some strategy games and need to control 1000 units or more I may change my recommendations ... maybe ... 😉

Maybe a better page covering the cpus you're considering or very close - and all tested with a 3080:

I would stick with your current rig and just upgrade the GPU (and maybe add one or two more SSDs). Canada Computers has had RTX 3080 Ti stock for the past couple weeks. Last week most stores seemed to have multiple models in stock, and there are still small numbers trickling in every few days. I almost pulled the trigger, but decided to wait and see if they start getting 3080s soon.

DK2, CV1, Go, Quest, Quest 2, Quest 3.


Try my game: Cyclops Island Demo

I know i could wait and throw a gpu in my current computer.  But the 3080s and 3090s are hard to get on there own and to pay retail if they come its almost as if there giving away the computer.

Also i want to experience full link capability and some titles with a 2080 super just doesn't cut it.
so do you think the i7-10th gen won't dip with a 3090?

If you want to see real differences between cpus, you have to go low to remove the gpu bottleneck. In 720p you may see the theoretical differences which you almost never will see in the real world:

So i7 10700K is about 5% slower than the 10900K - and according to TechPowerUp the 10900K is still the fastest gaming cpu Indel ever made, even a few percent faster than 11900K.

But 5% at the max is really nothing. Get the fastest gpu you can get, and the i7 10700K is already more than you'll need in current games. 

 

Btw, Pyroth309 measured up to 22GB vram use when Reviving Asgard's Wrath with the Reverb G2 using res 230% (game still playable). It seems that high-res hmds can use a lot of vram when you start to super sample.

To me getting the 3090 wasn't primarily to get 20% more perfornance than 3080, it was getting more than double the vram. Better safe than sorry.
