GPU Stream Rendering on PCIe 2.0?

[ComponentOwl933]

I am looking to upgrade my PC here soon when I get my bonus check from work (because overkill) and I am wondering if anyone knows the limitations on stream rendering using an RTX 2070 in a PCIe 2.0 x4 slot and whether or not it would be worth it. I am trying to eliminate any stress on my main GPU (Future RTX 2080ti running at PCIe 3.0 x8). I have a Samsung 970 EVO NVME 250gb in my other PCIe 3.0 lane restricting my first and second slot to x8 and the third slot is only a PCIe 2.0 x4 lane from the chipset. Specs are as follows for the complete build for reference.

Case: Corsair Obsidian 750D Airflow Edition

PSU: Thermaltake Toughpower Grand RGB 850W

Motherboard: Gigabyte Aorus GA-AX370-Gaming 5 (rev. 1.0)

CPU: Ryzen 7 1700 OC'd to 4.15Ghz

RAM: G.Skill Ripjaws V DDR4-3200 CL15 32gb 4x8gb

Boot Drive: Samsung 970 EVO NVME 2tb

GPU1(Main PCIe Lane 1): RTX 2080ti or RTX Titan (Haven't Purchased Yet)

GPU2(Current Main PCIe Lane 3): RTX 2070(This is the question of whether or not it is worth it to use as a render card or just sell it and go with the Titan?)

Cache Drive For Steam Drive(PCIe Lane 2): Samsung 970 EVO NVME 250gb

Steam Drive: Samsung 870 EVO SATA SSD 4tb

Raid 10 Storage: 4x Toshiba HDD 7200RPM 4tb (Don't remember the model)

Just get an rx 560 or something to do stream rendering then. Or use the CPU.

 

You dont need a super powerful GPU to render streams.

I am upgrading the main GPU either way and it would just be easier to keep the current and use it instead of selling and then buying another one as well. I am just seeing if anyone has tried any testing of limitations on using the PCIe 2.0 x4 lanes instead of the PCIe 3.0s for rendering purposes(not just stream rendering). Eventually it will be put in a second PC when I ultimately get a new CPU and Motherboard (maybe Ryzen 9?).

Id sell it and do CPU rendering untill you get Ryzen 9
