I've got a i7 950 o/clocked to 3.4GHz (mild), 12GB DDR3 RAM at 1800MHz, HD6970 graphics, Intel SSD.... and it's sitting unused under a desk in another city



At the time, this cost like $2000 AUD but it was bleeding edge. You could prob pick this up for like $800 and it will play the **** out of minecraft (and everything else).
Whats the major bottleneck for Minecraft? RAM, CPU, HDD or GFX?
Focus on the bottleneck if you want it focusing on minecraft
