Over the years I have , not lost interest in the latest tech....but I have got more sensible with upgrades etc...CPU tech hasn't moved on much IMO since the massive jump that was Conroe from previous available tech available at the time...
I'm running a sata 3 SSD on a sata 2 port and I'm losing no sleep...they destroy the raptors for an OS drive.... When raptors were the only thing available at the time....would I get a faster boot in windows moving it to a sata 3 ? The answer is yes but it would be negible.
Usb 3 ....don't really need it....
A lot of the tech is of course faster but not life changing....a lot of it is marketing...and go faster stripes and numbers....
When my gtx 970 runs the same in a pcie 2 socket has it does in a pcie 3 socket you have to have a serious chat with yourself ( well myself

)and think maybe money could be spent on areas that are life changing like a 1440p 144hz monitor and the like.
All my multimedia and photos are store on the server that I acess over gigabit Lan... My setup is quite sweet and certainly on par with the lastest and greatest costing three times as much.
EDIT: I have done water and phase change and overclocked the ass of hardware for years....I'm glad I'm sensible enough to jump of the must have the latest merry go round lolAs long as I'm not uber behind I'm fine with it if I'm honest....latest tech can be scratched with gfx cards....and the 970 proved to be great at just that....
