I'm waiting to place a pre-order for a 4090 and a subsequent complete new build. I've struggled through with my old 1080ti, which has been having some challenges recently. My useage is both work (artwork / video) and gaming (on the same machine).
The question sits as:
Do I go Intel Raptor Lake or AMD 7000 series. I've been Intel for years, but not adverse to a change.
Then, is DDR5 worth it, or stick with DDR4 (my concern is it becoming out of date / obsolete etc).
Thoughts appreciated. The rest of the system will be overhauled at the same time.
So it sounds like you've got the budget for a high end machine and I'll tell you what I would do with your money if it was me.
Sounds like you can also make use of many cores as you're in the rendering area.
I just need to ask a couple questions: How good are you at trouble shooting problems on your PC? AMD can be a bit iffy with early BIOS versions (Intel have had their own issues too but AMD tends to be worse).
Do you use CPU or Cuda cores to render with? Either is fine. Cuda tends to be faster, CPU tends to be more accurate. If you use a bit of both, that's fine.
I would go AMD 7900X with a B650 motherboard when they launch soon and cheap DDR5. Even if you went Intel, I'd still go DDR5. You probably need capacity more than actual speed and DDR5 is finally cheap enough to justify in certain use cases.
I would also match your PSU to your GPU (when we know more about which models of the 4090 use ATX 3.0 PSUs).
Do I think it's a touch early to pull the trigger on the 4090 without seeing reviews first? Yes. Do I think it matters that much to your use case? No. You'll still make good use of a 4090 given that it's for work.
You could get a 3090 on sale mind you and save a bunch of cash. You could also get a 13th gen Intel CPU and pair it with a Z690 motherboard and save some cash.
Do I think AMD are expensive? Yes. Do I think AMDs new CPUs are very very impressive? Also yes.
The best bit is that there is finally some choice. You're probably going to be happy with either.
We can put together a build ex chassis which you can choose yourself.
