Hi, I see very nice rewiews with i7 920, old xeons, 2 nd gen i5, i7 and etc. It's hard to decide, older i5, i7 for 20$ still performs great these days, i know it's outdated and etc., but I also didn't played older games few years ago. Main priority is money saving. I also see nice rewiews with i3 6100, g3258 and etc., but these are more expensive. So need some recommendations what to do?
