Question / Help StreamPC "upgrade" advice..odd current setup.

Hello everyone,
My streamPC is an HP Z600 2x Xeon 5650 with a 750ti. I can stream 720p60, x264,medium, without issues, but im looking at possibly increasing the image quality of my stream (pixellation likely due to outdated hardware) or even attempt 1080p60 streaming either by :
1. installing a Turing chip GPU in the stream pc
Or if I must,
2. upgrading CPU (which means building a new PC and sticking with 770ti as GPU).

I understand that 6000 kbps (twitch) is not the preferred bitrate for 1080p streaming, however I do see other streamers do it and I would like to try my hand at it as well. I would like to find the most cost effective way to be able to stream 1080p60 on twitch without encoding overloads. Basically I want my only potential hurdle to be bitrate.

Basically, Im asking everyones opinion on what they would do in such a situation, given that NVENC (new) has made some major improvements.

Thanks!

I would probably buy a Turing card (since I already have) but it's difficult to know exactly what you think is low quality in your stream and why, if you're currently holding x264 medium without frame drops.

Turing can do 1080p60 and it will look about as good at 6000 as it can, and likely better than it would likely look if you ran x264 on that machine at the preset it could hold for 1080p instead of 720, which I imagine would not be medium.

At the end of the day, though, there's no substitute for bitrate, and you might even do both CPU and GPU upgrades and still decide you like the look of 720p60 better at 6000 than 1080p60, no matter what you're encoding it with.

I'd still do the GPU upgrade first, not only to get Turing, but to move on from a GPU that is seriously long in the tooth by now.

Exactly! Iw as considering a 1650 super, BUT the card uses PCIe v3, and my streamPC uses PCIe v2.
I have been reading that newer cards do not fully use PCIe v3 lanes.

I am wondering if anyone knows if I can install a 1650 Super in my streampc using PCIe v2 and get bottlenecked on the PCIe lanes?

It should be compatible but I can't say it wouldn't bottleneck as I don't have a machine with PCI 2.0 only slots.

I don't imagine 1080p60 would cause that, though.

PCI-e 2.0 slot with PCI-e 3.0 graphics card.

Hello! My name is Kostas and I want to ask a question regarding my GA-EP45-UD3LR motherboard and GTX750 Ti 2GD5/OC that I want to upgrade my graphics card to from my GTS250. My question is will the GTX750 (PCI-e 3.0) work with my motherboard (PCI-e 2.0 slot)?

oh damn I had not noticed the 750ti also uses PCIe v3....

As a reference, this was a stream i did yesterday with my streamPc using the 2x Xeons: https://www.twitch.tv/videos/560382652
I can get down to medium under 720p60 without getting encoding overloading issues. Buuut I think since hte CPU is pretty dated,720p60 on this would look different than 720p60 medium x264 on a ryzen cpu..

x264 medium is x264 medium. The encoder doesn't care what CPU is doing the work as long as it can do the work. If the CPU can't do the work, it won't look worse-- it'll drop frames.

Ok I was wondering that. I just thought with newer hardware, comes better x264 technology and maybe had some tweaks or something that would improve the yisual quality using newer hardware.

So then maybe getting the 1650 super would be my best best and using the new NVENC in obs and would likely look better than my current x264 setup

Don't by a GTX 1650, if you want it because of Nvenc. It has a Pascal Nvenc encoder, not a Turing Nvenc encoder. The GPU is Turing, but Nvenc is Pascal. The GTX 1660 and RTX has Turing Nvenc.
