I would but I have a faulty CPU It gets buggy and refuses to work properly with my RAM, (My CPU is bloomfield (and a LGA1366 socket which isn't produced anymore), so it might also be simply because the model is so old), but as you mentioned yourself, I'll go through the trouble of once more overclocking the CPU and getting my RAM working with it when it starts to fall behind. (That or I upgrade it).

When I bought my current system it was so that I could keep upgrading it, so I bought an' expensive foundation, making it easier to just change the single components as needed, my next upgrade will need to be the CPU, but I've got an i7 Quad, 3.3Ghz (easily overclocked) so I'm still good for a couple of years.

I have an i5 2500k and it's @4 from 3.3 atm, I looked on the Intel website and they're on gen 6 or something now and mine is a gen 2 yet no game is really giving it any bother at all yet, especially with them getting better with multithreading. I can probably just OC it to 4.5/4.6 when it starts to fall behind too.
You should do a moderate OC straight off the bat as you'll actually reduce the Vcore because it gets set sooo high by the autocalc. Mine is lower than @ stock when it was 3.3.... Obviously PLL and the load settings are higher but the Vcore went down so that's a possible wear reducer.

I got a 970 as well, and trust me, the 970 is a rather high end card and you'll be enjoying it for plenty of years to come.

Yeah, I think a nice time to upgrade is when you can get a 100% performance increase without spending your life savings, which is what this card was from my 6970 before. 'Luckily' the old GPU was a massive bottleneck and my CPU can keep up with the new card but I think next time I upgrade it'll be closer to a new build than an upgrade.
