game-lover :
pls help i am not getting proper and correct answer and will i be able to play any game for 3 more years to 2015 on max settings
You'll need a couple of
these to have a reasonable assurance of maxing all games out for the next three years.
To give you some perspective, let me break things down a bit.
First, the FX-4100 is a really cheap processor. Shooters tend to be demanding of CPUs, so this is going to be a problem. You want a real quad core chip, not one of AMD's dual module chips they're trying to sell as quad core chips (they only perform like quad cores with purely integer workloads, which don't exist in games).
More importantly, you're expecting mid range cards to max out all games for three years. They can barely max out all games
today, and only if you're fine with framerate dips. For reference, I have a pair of overclocked 7970s, and they only manage a bit over 70 FPS on Far Cry 3 on max settings at 1080p. In three years, they'll probably be getting more like 30-40 FPS on the demanding games and your mid range cards will be totally unplayable on max.
