Pentium should be enough for MadVR. As long as you don't go for MadVR + SVP, the pentium will handle MadVR fairly easily.
Given MadVR latest improvements (NNEDI, OpenCL error diffusion), you might be a little under-powered with a 7790 for SD and 720p content. But if you are going to watch mostly 1080p and/or will be happy with Jinc upscaling, then 7790 will be okay. Full MadVR has taken a whole new meaning recently, just making sure you knew....
I would not even try to run a pentium in the same room as a machine running SVP
The two are like oil and water
As for MadVR you might want a corei3 for the hyperthreading and extra speed boost. Pentium is really pretty weak CPU for a serious MadVR machine. The high turbo boost alone on the i3 makes is a better choice for headroom- it will let your video card work easier and give you better results. 7790 is probably enough but those cards are gone now. With a Pentium is would be more important to spend up and get the 7790 with 2GB (asus is good choice) as you would feel/need the improvement over the cheaper 7770 with only 1GB. Video is harder than film (60fps vs 24fps) so for film you mostly will be ok, but with video not so much.
Of coarse with Litecoin mining now all the radeon cards are sold out and increase about $100.
You can not find good prices on 7770 or 7790 cards (they were selling for $100 or less for a while). I doubt you even find any in stock or left. They are now old and discontinued.
The replacements are the R7 260 and R7 260X I would suggest the R7 260X with the i3 for some extra headroom. This forum has a tendency to reinforce the mentality of "enough" or going "cheap" but often this bites you later on with regret or less optimal performance. Nothing wrong with a little extra just in case, you often will be glad you did later.
I have learned this lesson the hard way. Upgraded my desktop 3 times in last 3 years, upgraded my server 3 times, and upgraded my HTPC 3 times. I started on a PENTIUM for my HTPC and my server and both have been replaced. I have a 3570k now in my HTPC and an i7 2600k in my Flexraid media server. My desktop is a 4770k.
Pentium is fine for simple play back duty but when you get into serious madvr you likely want an i3 or higher for many reasons. It's not about if it's enough all the time either. It's about what is best choice or good decision. Unless you have a super low limited budget you don't want a pentium.
Many think the pentium is more efficient or more "green" which is also a wrong myth. It will actually run closer to 100% or higher in the percent of CPU needed for such things, so it will run hotter and consume more power. On something like a modern Haswell i3 just because you have 3.6ghz clock (higher with turbo boost) does not mean it uses more power. Actually probably uses less playing back a video on madvr, and it will idle around 800mhz. But if you need the power and when you want it (like opening a heavy program or winrar something) it's well worth having.
The difference in cost of say a 7770/R7-260 and a R7 260X is about what the difference between a pentium and i3 are. You might want to do the lower card with the higher CPU, I think it's more balanced.
R7 260 + i3
next level up would be"
R7 260X 2GB with i5
Chasing madvr is a serious en devour so if you are the type of person to care about such things as opposed to simple playback (for which pentium is wonderful) I tend to think you won't remain happy with a pentium. I did not.
If you want Nvidia you need at minimum a 650Ti.
