Greetings B-Riz,
SuperBiiz has $5 off $25 right now, could try a G4560 and go i5/i7 (maybe used Xeon?) later;
G4560 seems like lower pricewise, the main diff for my needs is the clock, smartcache and the avx, the rest is not interesting, I do wonder if it is better to get the G4560. I don't intent to upgrade the cpu later on, so if futurewise is important (not sure how it will), than the i3 is the better choice.
and pricewatch has a nice selection of cheap Gigabyte H110 (2 ram slots $40) / B150 boards (4 ram slots, $50).
where I live, the cheapest board I've been able to find is what stated above, I don't mind having just two ram slots, it is cheaper to buy 1 chip of 8Gb rather than 2 of 4Gb.
There is always the option of an R7 1700 that is getting cleared out with a nice under-volt.
the R7 1700 costs 2.5 times the i3-7100, for less than that, I can get an true quad like 8100 and finish the debate.
