How about i5 6500/i5 6600t or something like that they are around 50-60 euros.there is a late 2016 BIOS that says 'supports next gen Intel CPU', but, that is hardly definitive or 'confidence inspiring'....
h110m pro vd supports 7th gen cpus. https://www.cpu-upgrade.com/mb-MSI/H110M_PRO-VD.htmlan i7-6700 is nice, but, not sure if it's price will be a 'bargain'...;$225-$250, for instance, would get a new B450 and an R3-3300X, which lays waste to the 6th and 7th gen Intel CPUs in gaming)
Unfortunately, I can't find any online evidence at MSI's website evidence that the H110M-Pro-VD supports any 7th gen CPUs. (It might, but, I can't find it!)
