Simply, I only want to play 3D iso movies on discrete video card in a quiet HTPC without bother any high MadVR levels.
Why not just use iGPU ?
Like I said to OP just stick with what he already has. HD4000 is fine. I use it myself. My 3570k i5 only had HD4000 graphics. It's perfectly acceptable for playback and 3D. I can even do MadVR level 5 on film and madvr level 4 on video with a mild overclock of the iGPU. It's not bad at all.
It's simply not worth buying a GPU card that is only marginally better than your igpu in your CPU. Adding any GPU is going to increase power consumption, heat and noise. The difference between say a 7790 and a 6750 is really small. The difference between a 6570 and none is pretty big.
I tend to be the guy that always yells "go big or go home" so I might be biased here but I would just stick with iGPU or go all the way with a card that does full MadVR. Like you just said, it's only $60 ($100 with less good sale)
I'm not sure if you guys are aware or not that you can run off the iGPU instead of the GPU card when you want and save energy ? You do know this right ? Just because you install a GPU card doesn't mean it will run 24/7.
I use LucidLogix Virtu GPU (came with my Radeon card) Basically it regulates if I need a GPU card or not. If high end graphics power is needed for applications like DirectX 11, high-resolution 3D gaming, the system will assign the job to the discrete GPU. If not, the discrete GPU automatically goes into idle mode, while heat drops, fan speed slows down and GPU utilization goes down to zero, resulting in a green, power-efficient, long-lasting system.
Free with AMD RADEON cards and use with INTEL CPU's
Not sure the objection to the better video card, as I still think either do it or do not. No point in doing it half way IMO. It's not worth the cost and the effort to install a GPU card. Perhaps if you had a CPU that did not do 3D and you only wanted 3D then perhaps a $50 GPU card like cheap 6000 series might make sense, but now that you can get higher end 7000 series under $100 that's probably the best choice.
AMD is making a 9990 prototype (they renamed it R something or other) that has 12GB GDDR5
now that baby is probably overkill
