Ok, this is where things can get very dubious for you if you aren't somewhat educated to the hardware specs that are required by your software, and also your current hardware situation. Unfortunately, I am limited as to my recommendations based on the information you can provide. Understandably, this can be a confusing topic even for some intermediate graphics enthusiasts so let's tread lightly to start with. First, let's find out exactly what hardware you're running on your machine. I know you're looking to upgrade your graphics card, but in order to know for sure if that will be the biggest benefit to you right now, you need to make sure two things. First, make sure the software you intend to render with can utilize the GPU acceleration fully, and which GPU architecture the software uses specifically for GPU accelerated rendering. This should be the very first step. You may be thinking you will benefit most from a graphics card, but if the software you are running is merely GPU enhanced rendering, and not fully utilizing the GPU over the CPU, then your CPU will still be the biggest bottleneck in terms of render speed.

For example, there are some render engines that use the Computer Processing Unit (Intel i5, i7, Xeon, etc) to do most of the work during a render, but will allow you to include the GPU cores, if you have any, to assist the CPU in the rendering process. These render engines will still use the CPU, but incorporate any GPU cores in the rendering as well, like little helpers. I do not use Poser, so I do not know for sure if the render engine there allows you to use ONLY the GPU for rendering (which puts all the load on your graphics card entirely), or if it's using GPU assisted rendering which means the CPU is still doing most of the work and still involved in the rendering process. Also, I do not use Vue either, but I can do a quick search on that one for you if you like. Pret-a-3D's Reality engine, I believe, uses GPU assistance rendering if you choose it. This means it's still rendering with CPU, but involving the GPU cores if it can. Daz Studio's IRay engine, on the other hand, can do CPU, GPU, or both. This particular engine is very versatile, and it would benefit you greatly to have at least a GTX card with 1000 or more CUDA cores, like the 1060 I mentioned earlier.

First find out for sure if the software you use can support CUDA or OpenCL rendering, or if they are simply GPU assisted, and still using the CPU for most of the work. Then find out exactly what CPU processor your system currently has, if you can. For example, is your system a i5, 17, or AMD processor? It's important to know how modern your CPU is because most CPU's produced in the last few years can take advantage of a collection of high-performance ray tracing kernels, developed at Intel, called Embree. Almost all of today's CPU powered render engines use that to speed up renders. Once you have this information, we can recommend what the best choice is for you, or at least what we would do in your situation. I don't want to tell you to go buy a $250 GTX 1060 if your software can not use CUDA.

If you know exactly the make and model of your computer, I can just look it up for you and see what it's running. But I'd need to know the exact make and model number of the computer, if possible.
