Here is the gist of it.
I currently have a Pentium G3258 (the 20 year anniversary one), and despite its more than great performance relative to its price I am wanting an upgrade, due to lackluster performance in some of my favorite games, and in general desktop use.
Soon I am building a replacement PC for my brother, as his is barely scraping past windows 7 on its Athlon 2 x64, and thus I am getting his current PC in return. Obviously this would be no upgrade to my current system (check my profile for full specs), but the motherboard inside has an AM3+ socket, a 'modern' CPU would work fine. At the same time I am planning to upgrade to an I5 4460, as I can get one from CEX (UK second hand store) for £90, however I am planning an OS reinstall anyway, so If I could get an AMD CPU for the other motherboard would that be a better option?
I would simply like advice along with recommendations for AMD CPUs if that is a good choice.
