Sorry to tell you guys lately
But I don't play any multiplayer
Single player is not very cpu demanding
Thinking of that If I buy an fx6300 will it last for 3 years for single player games @720p
Short answer NO. There is more demand on the CPU and system overall, each new game needs 'more, be it the physics now instilled on why a mortar does Y damage but a .45 Colt does X damage, or how 'coordinated' the A.I is to work against you. 3 or more years ago I remember you could use a Handgun AS effectively as a Mounted Machine gun on the same wall. I also remember easier 'spawn points' to avoid or 'corridor' pinning the AI against a wall/etc. so you can headshot the 'dumb' A.I. Simple fact, even with "single player games @720P".
See my previous response if you want to "last for 3 years" on the games being issued in 2015, 2016, and 2017. If you want that sort of guarantee, as I said, go Consoles. PS3/360s been working just fine for 10 years and still going, can't be said for any PC to 'game' like that for HALF that time.
