every few years is recommended at most. but 6month old paste is not a great start to your new over-clock.
What im trying to tell you is that IF you want to OC a chip that has 6 month old paste on it. It would be a good idea to re apply the paste anyway. Its always a good idea to re apply the paste. The idea being to get the best results...
Which brings me back to my original point of there not being any point offering the high end goo.
Im not typing this out for fun, Im just trying to help you understand.
If I want to overclock in six months, but decide I can do it without having to reapply paste because I already have decent paste installed, then I'm fine with that. Currently that isn't an option though, which is why I suggested the 'option'. How is that different to buying a pre overclocked system which is still overclocked after six months?
Thanks for helping me understand though.
