Well, as a fellow user of Vray
, I guess i can help you here a bit
To be honest the jump from a 1090t to a 8370 is not that big as you can imagine, this is because your CPU have 6 cores while the 8370 have 8, this means only 2 more cores.
Now, the main thing is that Vray, is a software designed to gain advantage of multi-threading, this means more cores the better. It doesnt matter if 1 core is super fast, and that's the difference, AMD have higher speed per core, but Intel have more cores.
Regarding of which benchmark is realistic idea for rendering speed, well there are many, but the closest one to vray, is cinebench, so the best way to compare the rendering power of a CPU is comparing the Cinebench scores.
I will leave you here, so you can see for yourself what I mean by that.Phenom II X6 1090T versus FX-8350 Comparisons
Keep in mind that the difference between the FX-8350 and the FX-8370 is pretty much the cpu binding (Higher speed) other than that they are pretty much the same thing. So you can test yourself using Cinebench
and compare those numbers.
How much can you OC an FX-8370, well I would say probably around +4.5Ghz, it really depends on how good your chip is, and the configurations. sure you can hit the 5Ghz but dont buy the chip thinking that you are getting a 5Ghz Chip, you have to work for it
In case you want to compare Im using a FX-9590 @4.5 and this is my score
Cinebench R15 - Single-Threaded, Turbo core OFF: CPU (cb): 116
Cinebench R15 - Multi-Threaded: CPU (cb): 710
Does your mobo support the FX-8370 (Vishera)
Yes, but you need to update your Bios to F10eGA-990XA-UD3 (rev. 1.x)Socket AM3+ - AMD 990FX - GA-990FXA-UD3 (rev. 1.1) CPU Support List
I guess my best advice would be:
If you are starting to earn money from your work, or planning on being more professional, it's better to go with an Intel CPU, get a least an i7 with 6 or 8 cores, that will give you around 12 to 16 threads in total, and you are gonna kill those renders faster
Hope that helps,
