I think it depends on how you mean "future proof".
For someone (like me) future proof is a gaming rig with 700-800$ for 1-1.5 year with full graphics and on 2nd year buy a newest gpu (350$+).
For someone else future proof is a gaming rig with 1500$+ for 1 year maximum with full graphics, and on 1.5 year (because you might downscale Antialiasing by 6-8 lets say) buy a 500$ gpu.
It's all about smart buys. For example amd is more clever buy than intel because AM3+ will be for at least 3-4 years updatable and for the price.And yes it does everything a 2500k does maybe with 3-4 seconds delay which I DONT CARE about!
You'll still play the same game with the same performance with less money.Why not?
Ok for benchmarking wh**es intel is a way better than amd but i dont think like that.
Craver my Rig cost £1800:00 and i can tell you its good for 3 years no matter what games are brought out,it comes down to economics,No-Way are these studio's going to keep making games every year were you have to upgrade your Rig.
there are far to many gamers out there who just cannot afford this kind of money,as for buying a Rig for "Your words"
"(For someone (like me) future proof is a gaming rig with 700-800$ for 1-1.5 year with full graphics and on 2nd year buy a newest gpu (350$+)."
this kind of money I would not be HAPPY owning and relying on it to play top class games on PC.
P.S.My Rig was bought off the shelf you can check it out its a MEDION Erazer X81 and its made in Germany.
