Hello Everybody! Can you tell me something about i7 4790? I got an i7 2600...and I want to buy an i7-4790 + z97 gaming 5...is this worth for gaming? How many years can I handle videogames without cpu bottleneck with 4790?

True but he`s talking about future proofing until he should upgrade... The 2600 is a fine cpu and will be good until the end of the year, then you should upgrade. But that does not mean the 4790 is not a good upgrade, it is very very nice it`s just you won`t see the jump in performance I think your hoping for... The sandy bridge chips are still very good...

You have no ideea my friend what impact could have, it can close some junctions in the CPU and even if the frequency is unchanged it can cause a decrease of performance just from the PSU, also it can appear errors when u open stuff just because those junctions are closed, basically a CPU is a huge number of transistors which have junctions, based on the psu some junctions can work some dont.

I do not agree with your use of logic...

Are you hitting CPU bottlenecks with the i7-2600? For the most part, you shouldn't. If the games you are having issues with are poorly done ports or known problematic titles, those will likely run poorly regardless of how powerful your CPU is.

With Skylake only a few months off, it would make more sense to wait for that. Upgrading now only makes sense if you absolutely need a new PC in the very near future.

OK let take on the other way, when u overclock a cpu, even if it starts and boot into OS why it is not stable? Because of the voltage on the junctions (or temperature but we presume that we got a kickass cooler). What do you do next, increase the voltage aka junction voltage and become stable, this applies to a cheap psu, the voltage on the 12V line is so low that the cpu is unstable (thats why the maximum drop on the 12V line is 0.3V). If a psu has a 12V at 11.3v or 11.5v then the cpu will suffer a lot(decrease in performance) because some junctions are closed.

Good laugh, but no. Just no. Unless the psu isn't able to deliver enough power to the point of throttling components, there is no impact on performance at all.

The CPU does not care what the voltage on the 12V rail is because it is not connected to it. It is the motherboard's CPU VRM's job to take whatever the 12V rail is at and drop that down to the 1.8-2V intermediate voltage the CPU's integrated regulator requires and then FIVR drops that further down to whatever the CPU circuits requires.

You either have enough power or you don't. When you don't, it ends with the motherboard or PSU's under-voltage lock-out or the PSU's over-current/power protection kicking in and shutting down the PSU. You do not get any mysterious performance degradation. Dirty power on a marginally usable PSU will usually cause crashes or other stability issues.

In most cases, power is an all-or-nothing proposition.
