I'd get a motherboard with it as well, obviously.
cpuboss(dot)com states that it's better, but I'd like to make sure before changing from 4 physical cores to just 2+2 virtual ones.
It wouldn't be better. The 2500 runs the same or slightly better than that i3. Do some searching on google for the games you're interested in playing, many sites like techspot have cpu performance comparisons that include 4th gen i3's and the 2500k (which is the same speeds as the i5 2500 when it's not oc'd). I would toss cpuboss's bookmark right into the trash bin, they often don't have a clue and just randomly post results based on numbers or figure well if a cpu is x amount of mhz faster it's automatically x amount better performance.

Not to mention even though an i3 will often play games well enough that 'require' a quad core cpu, in games like witcher3 and others the i3 can often suffer fps drops and dips because of the fact it only has two cores even though it has hyper threading.
