Full upgrade or only GPU? Bottleneck?

RE-OPENING THIS THREAD. LATEST UPDATE FROM ME IS POST #20 PAGE 2

Hey all,

Currently I have:

i7 930
Asus P6TD Deluxe mobo
ATI Radeon HD5870
12GB RAM

I mainly use my rig for audio work and 3D work - rendering is important (GPU rendering is what I want to do and can't right now).

I am 100% moving over to nvidia and thinking about grabbing the 1080 TI - my question is - will this cause a bottleneck on my current setup? I'm thinking about doing a full upgrade but I'm not sure.

The more VRAM I have, the better! The 2080 is too expensive right now unfortunately.

In the long-term I would like the option to get 2-4 1080s for more power so I will eventually need to do a full upgrade but for now, short-term... what's best? Is my CPU limiting me?

I would be grateful for any advice from you all here.

Thanks!

Wait for Computex and see how Zen 2 is then make a decision about upgrading the CPU motherbord and RAM then
What PSU do you have in your system and yes that matters too

Can you drop a 6 core Xeon in the Asus mobo? Might be a small option for cheap. I have a X58 mobo that’s on a Xeon W3690 now that had a 1070, 1080 and currently a 2080 as of yesterday and have some benchmarks currently using it I did in the last day.

My PSU is: EVGA SuperNOVA 650 G2

I didn't think about Zen 2. I have already been thinking about moving over to a Threadripper too.

I was thinking about doing that with the Xeon a few years ago - but now i feel it's worth moving to a modern mobo and cpu so I can future proof for another 9 years ... my PC is currently 9 years old and has held it's own very well so I want to do the same again.

Would still be interested to hear how your 2080 is doing though!

Wait for Computex and see what AMD has on the way i think there are new Threadripper CPU´s on the way as well so the older ones might drop in price if you still want a gen 1 or gen 2
Computex starts at the end of may so its only a month away

Here's some runs I did on TimeSpy currently in the last few days, GTX1080 & RTX2080.....I have my i7 7700K in there OC at 4.8Ghz I believe with 1080Ti....the W3690 is OCed @ 4.4Ghz or so...1080Ti & 2080 are deemed about the same in performance...but you can see some differences in these results.

Some other tests with just the W3690 & RTX2080 (RTX2080 is EVGA XC Ultra Gaming)

If you intend to get the 1080Ti, get it and run tests while on load and see if the CPU is bottlenecking the card. Best way you can gauge if these rendering workloads would do that. For gaming I'm sure there would be especially on 1080p.

If there is a bottleneck see what Ryzen 2 will offer.

It's not just GPU usage that will be low - his CPU is very weak nowadays and even without chocking the GPU he'll lose a lot of FPS only due to the CPU not being able to provide needed performance.

Thanks everyone.

I've decided to sell my rig and start fresh.

My rig is 9.5 years old so it's time.

I'm focusing on GPU rendering and want the capability to add more GPUs in the future. 2 or 3 altogether most likely.

I need to build a system that will last me a good amount of time like my current one has.

It depends on the release date of Zen 2 as to whether or not I wait. I don't want to be waiting too long tbh.

We'll know in one month when Zen 2 launches. Considering you want to buy once and not upgrade your CPU in a while, I'd definitely wait for the Zen 2 announcement. How much are you willing to spend? If you really can't wait, current threadrippers are not bad at all, and there are some great deals coming up regularly.

Also, what software do you (want to) use for rendering? Depending on that, Radeon might still be a good option;

If you want to use 3 or 4 cards, make sure to get at least a 1000W PSU.

RAM is quite cheap right now, so getting at least 64 GB shouldn't be a problem.
