Why is my i5 2500K at 5Ghz still so great?

Looks like the 2600K will be as great a value build as the prior Q6600 build which my mother still uses was. I see no great need to upgrade until there's at least a 50+% increase in raw single threaded performance which looks to be years away yet.

It's not like I need to save another 5 minutes using handbrake with that bluray or need the extra CPU power for some CPU bound game or anything. The 2600K does everything I need it to do.

I may upgrade to Haswell-E next year depending on what new features are brought to the table chipset wise.

You're already looking at +/- 20% for haswell, assuming Skylake improves upon Haswell another +/- 20% you're pretty close to your 50% requirement. Question will be how much OC potential is left after Intel goes full on power savings.

Core2 to Nehalem wasn't a 50% increase, it took SB to get close to that. Likewise Haswell isn't 50% over SB, but it made a similar stride to previous generations. Skylake will be to SB what SB was to Core2.

(assumed)

FYI -- i7-2700k @ 3.9 GHz DDR3 @ 1600 I score about a 7.6x in cinebench -- more / ghz??
