The only difference is the GPU systems are a pain in the ass and the ASICs are more of a 'set it and forget it' item.
so fanatic26 hated GPUs because they are not "set and forget"...imagine the trouble of running them by the 1000s? haha ...and also imagine him managing 1000s of GPUs....and he is thinking "those damn kids making the difficulty higher, i hope their gaming PCs and trash DIY rig explodes!" haha

and also when fanatic26 is purchasing GPUs....i wonder how many times suppliers "limits" his purchase??...pain in the ass indeed..
