cpu/mb/ram upgrade from i7 920 / X58 / 6Gb to current gen ?

[Bokothor]

Hey everyone,

I'm currently using the aforementioned system as sort of a multifunctional machine. Gaming, some music recording, browsing, movies, etc. I'm considering splitting up these activities to seperate rooms for reasons such as comfort and ergonomics.

So, i'd like to build a new PC while recycling the GPU from this machine, an R9 280x.
I'm someone that doesn't upgrade cpu/mainboard/ram once a system is built, unless one of those parts breaks down, so to be hasslefree for lets say the next 5 years i need something reliable and futureproof.

I've got my eye on an i7 4790k, some Z97 mobo with crossfire/sli potential for later, and 16Gb of 1866 Mhz DDR ram.

My question now is, with the same graphics card, how much of a performance / fps increase would this new system yield over the older generation rig ? It's both i7's but several generations apart, the 920 is about 5y old. I'm not entirely sure but i think i have the 920 overclocked at 3.6 Ghz, while the 4790k is 4Ghz stock, but goes up to 4.4 easily.

Any insight on the matter ?

Thanks in advance!

It would be quite an upgrade, about 30% in completely cpu bound scenarios, such as non gpu-accelerated rendering. In gaming, with a r9 280x, you mostlikely wouldn't really notice much difference. Depending on the game possibly a few frames more, mostlikely only measurable, though. Either way, getting new ram would be pointless, as the i7 4790k also uses DDR3 ram, just as your current one. For browsing, music recording or watching movies, there won't be the slightest difference.

If I were in your position, I wouldn't upgrade now and probably not until sky- or cannonlake. Performance improvements of the last generations have just not been enough to justify spending a $400 for only ~5% IPC increase.

Well, with that in mind, i might just opt for 2nd hand system similar to mine to bridge the gap till a real upgrade makes more sense, i'm not displeased with my 920 yet, i just need it to be in another room (too) . Thanks for your insight.
