Yeah I get that, believe me I've been there , but why specifically? Unless it's distant future proofing or high end video editing, neither are really that worth it right now if it's just general multitasking or games. Don't get me wrong, I run an i7 myself, but that's purely because I got a great deal with a decent overclock, but even then I never use the OC and I doubt I'll need to even into the future gen of games. Sadly
But bare in mind that you also need to look at single core speeds and performance, as a lot of games still don't properly utilise multi-cores, at least as not as much as they should. AMD have always played on that and boasted about having loads of cores, performance and all that, but when it comes to games and general use, the i* cpus actually outperform. But like I say Ryzen might be different, I haven't looked in a while at the actual figures, but it's the same sort of thing they've always said. Also with the intel processors, some higher end models do end up looking like very slight upgrades on the much lower and cheaper models, but that's not always the case at all, all sorts of things affect performance in different ways, that's why it's important to look at what you use the computer for most.
