This is true, but it is a benchmark situation vs real use, for which my original question was won't it be worse if other stuff is running in the background since there are no extra cores to take on more work?

It doesn't run as fast as those cpus but it gets fairly close.
Is everyone sure about that? It would seem to me that the G3258, which is a dual core chip, would be noticeably slower than the i5/i7 because all of the other windows processes need to run on the same threads as Dolphin. This could lead to major slowdowns, especially if this is a true HTPC which would make it internet-connected with antivirus and media streaming such as Plex. I'd almost rather try an i5/i7 with no graphics card in a smaller case and pay a little more for a good cooling solution than to use the pentium...ESPECIALLY if there's the potential this PC might be used by more than one person at the same time (i.e. streaming a video to one TV and Dolphin on the main).
I'm not sure what your budget would be like, but provided you have enough money you can get something with the 4770R processor and Iris graphics, eliminating the need for a GPU if all you're doing is Dolphin in terms of games.
TL;DR the G3258 might be similar in benchmarks, but not in real-world use.
Haven't taken a look at processors with Iris graphics, is Iris graphics succifient for scaling up to 720p and 1080p? Do they require alot of power from the PSU (the cases I'm looking at will most likely not have potential for a PSU over 300W)? Sounds like something to look up, since it would fit very nicely into the case to not have a discrete graphics card.
The computer will not be used by several people at the same time as you describe but ofc it will run some background stuff, especially since i will use Windows (but maybe Linux also).
Keep the info coming!
Thanks!
Well I have no personal experience with the Iris Pro graphics, but I was able to use 2-3x IR on a GT 540M which according to notebookcheck.net is much worse in performance than the Iris Pro. Not only that but I have had several people tell me you can achieve 2-3x IR on intel HD graphics, so I would imagine the Iris Pro can do even better. What would really take performance hits would be improved AA, AF, shading, etc., and probably directX over OpenGL. Someone with more experience there might want to verify that though?
Oh ok, I was under the impression that it was necessary with quite a bit more than intel HD graphics to scale up to 720p/1080p (1080p corresponds to 3x IR, right?). But with that in mind, how well would Radeon r7 250 perform regarding scaling capabilities? If r7 250 if sufficient for 2-3x scaling that would be great, as it would fit my case very nicely.
. So, in order to fit the HTPC without having to move too many of my other things stored in the TV stand I've been looking at
