Computer suggestions for minecraft?
I have 32Gb of ram, Intel i7 3.2Ghz, NVIDIA HD GfX 4000 Graphics card. And coolers. The game runs with fps's with max settings up to 70 - 90fps.
In your case you only need a computer or laptop with the following specs, minimum of 8gb ram this will help. It runs run's best with this much ram or more. A CPU processor AMD or Intel. A good high powered and CPU, around 4 cores with 3ghz of power. Intel, a quad core 2.3ghz or the following. I3, i5, i7 any of those chipsets. And a good or reasonable graphics card. This should set you back to 500 dollars or less.
Pbtech is the best place to go for reasonable, cheap gaming pcs
What about using the current computer you have? If it's fast enough and you haven't added more memory or a better graphics card than the one it came with, you are sorely losing out on power. This is only a suggestion which will prevent you from wasting $300-500 on a new machine when yours will kick but when upgraded.
I can also suggest using linux instead of windows (ie. Linux mint), which then you can run minecraft on it. There are a few articles on how to get it up and running too.
