I've been building PCs since the the i486 SX days, used to connect the bridges on Athlon T-birds using a pencil to unlock multipliers, used to cut up heatsinks back in the day to make ram sinks, custom gpu cooling and volt mods, and even used to do the vapochill stuff during the madonion/glory days of PC. NVidia cards (even back to the first Gforce) just don't last.
Most of them died after a year to year and a half. Only the 980TI died quickly
And you still have not learned how to build them properly? :)
Every nitwit can overclock components, only a master can make it work properly for the long haul.
Just because it is stable for the moment it does not mean you have succeeded. Components are made for certain amount of stress and they are set accordingly. Some components can take more than others.
And it takes a master to know which ones might last for prolonged periods and with which settings when OC.
I have been building and OCing comps ever since I got my first Commodore. Ever since IBM PS/2 line was introduced in 1987 (used an 8086 processor and had an ISA bus which was the true beginning of PC as we know it, grandaddy to all later CPUs).
Ive had every PC component you can think of and CPUs ranging from IBM, Cyrix and AMD.
Today I build water cooled PCs (even tried a fully enclosed mineral oil cooled one once) which I never overclock past 20% of their base (history taught me).
Better to have good performing long lasting components than short lived record breaking monsters which cost your wallet.
