So, here's what I thought would be a good combination:

-INTEL CORE I7 4770 (approx. 380€)

-Gigabyte G1.SNIPER B6 B85 Motherboard (approx. 125€)

-RAM: Kingston HyperX FURY Red HX313C9FRK2/16 (approx. 150€)

A total of 655€ which is not too bad considering that it should work together quite well and that it does not need a videocard. And may be able to get all these components with slightly better prices.

I don't need to buy a monitor because I still have one that still works. The only thing I need is cooling ,a case and software.

This was just what I think is a good deal for quite a powerfull build. Maybe some things will change.

Don't forget to get a Power Supply! PC Part Picker was a very good tool for me to use, when I was building my own PC.

Youre right. Thanks.

Ive done some more research and the Intel Xeon E3-1231 v3 maybe even a better choice. It has no videocard included like the intel e series, it is much more powerfull and costs about 80 euros less than my previous choice.

Now you're making me think about getting a new processor...  undecided
An imporntant thing to look for in processors in regards to fractals is a good single core speed, which that processor has.

Getting a powerful graphics card only costs about $150, which is a good deal, especially if you are saving $80.

Do I? Thanks for your comment. Because there are some unused laptops here I may be able to the gpu of one of those.

speaking of that. Ive looked into the xeon e5 and e7 series and they dont seem to have a better speed compared to the xeon e3 series. But they do have more cache.

I found a very good combination:


The GIGABYTE GA-B85M-HD3: approx 50 €

Intel Xeon E3-1231 v3: approx 270 €

and Kingston HyperX FURY (8gb to start, will maybe be upgraded to 12 or 16)  60€


In total approx: 380€

And maybe even a better choice than my previous combination.

Ive been looking for intel cpus but some amds have a faster clockspeed.

The AMD Black Edition - AMD FX 4.7 GHz Processor
Has a speed of 4.7ghz and can even be overclocked to 5ghz, it has the same amount of cache as the xeon I chose and it is much cheaper!!!

Don't!!!!!!!!!!!
AMD processors get less work done per clock, so gigahertz doesn't matter. I make that mistake myself, already.

Unfortunately, Intel does not have a competitor at this time. Since 5 years or so, actually. AMD's CPU offerings are currently no alternative for fractalists. Intel's "Core" branded processors get maybe 40% more done per clock cycle. That holds for most single threaded software; the gap even widens a bit for heavily multithreaded programs.

Worse, the fastest AMD processors share one floating point unit across a pair of cores. So the typical CPU bound fractal application with many threads of heavy number crunching will make Intel processors look even better in comparison.

(There is only one last remaining tiny niche where AMD's offerings can outrun Intel: heavy arbitrary precision arithmetic based on wide integers. But this is no longer relevant for fractalists, because nowadays a new class of algorithms is used to render very deep zooms. Rather than relying exclusively on arbitrary precision arithmetic,  we use perturbation theory now.)

Good point. I will be using perturbation so floating point is essential, if intel is better with floating point I should choose the intel xeon 1231 v3. The same for multi threading.

i7 4790K + nice heatsink for overclocking
32GB DDR

Take that CPU and put it at 4.4 GHz, done.

In one of my previous posts I talked about overclocking but im not really planning on doing that. One other point is that im not sure if the 4790 is better or not compared to the price. But the speed of the 4790 seems reasonable
