I can totally agree with these sentiments. My first computer was a Commodore 64. Since then, I've been chasing the performance dragon, upgrading to a new computer every couple years. C128, Amiga, XT, 286, 386, 486, Athlon, P60, P2, P3, P4, P5... up until my last two computers.
My previous PC was a Core2Duo e6600 (circa 2006) and its performance was great and then still good. Had it for 5 years. I assembled my current desktop, a Core i7 2600k, in mid 2011. I've upgraded the video card (I'm a gamer) a couple times, and I was starting to feel a little performance pinch about 12-18 months ago, so I upgraded my OS drive to a 512GB SSD. I'm back to having zero performance problems except when fast traveling in Fallout 4 (my games drive is a mechanical hard drive.)
I've been considering another upgrade... but only if I can get M.2/NVMe and DDR4. I'm hoping that all of the announcements we heard months ago about new faster, affordable storage will pan out. Based on the hype, I'm hoping to get a few blazing TB of disk space for what mechanicals cost right now... but I won't hold my breath.
