Is it worth to reuse my old CPU??

[Zomboss99]

I want to build a new Gaming PC, but as you know CPU's can be quite expensive. My old PC already has a nice CPU that's around $400 (Intel Core i7 4770). I've only used the PC for around 3 years and I would save a lot of money by using this CPU. Has it lost performance and should be replaced? If I were to replace it, I would get a Intel Core i7-4790K.

My setup for my new computer would be:

Uh, the 4770 is only 2 years old about. Keep it, replacing it for such small benefit you might as well flush that money down the toilet. It's a great CPU capable of the largest tasks.

4770 is more than enough for current gen. The 4790 mainly brings better thermals to the table (in addition to marginal clocks), the 4770 is almost identically capable.

Stick with the 4770. It's even based on the same silicon as the 4790K, just binned lower. You will be more than fine.

Has it lost performance and should be replaced? If I were to replace it, I would get a Intel Core i7-4790K.

If this is not an unlocked chip, your 4770 will still have several years in it for games. As stated before the 4790K doesn't really add much unless you really are happy with maxing synthetic benchmarks.

From what I've heard (what anybody has heard) the next Broadwell release won't provide a tremendous amount of increase, but performance/watt may me noticeably improved. (Assuming LGA Broadwell isn't vaporware)

Skylake LGA (again, assuming not Vaporware) promises more, but everything released so far has been unsubstantiated and unreliable leaks. I'm going to upgrade my Haswell CPU with Skylake, but I have a locked 4770S (65W) chip. (Even still, that isn't being pushed by my few games, so I don't really need the upgrade.

If you can re-use your CPU, do so. Use the savings for a kick ass GPU.

As others have said, keep the CPU for sure. The best gaming CPU is generally considered to be a 4690K, here is a comparison between your 4770 and a 4690K:

UserBenchmark: Intel Core i7-4770 vs Core i5-4690K
Effective CPU Speed: 85.4% vs 90.9%
Intel Core i7-4770 - 17th / 825
Intel Core i5-4690K - 4th / 825

There is less than 5% in it.


The other change I would make is to a better SSD, the V300 is possibly the worst possible choice, go for a samsung 850 evo which is nearly twice as fast, comparison here:

UserBenchmark: Samsung 850 Evo 120GB vs Kingston SSDNow V300 120GB
Effective SSD Speed: 94.4% vs 44.6%
Samsung 850 Evo 120GB - 34th / 655
Kingston SSDNow V300 120GB - 482nd / 655
