File Conversion, Storage, and Software Development PC (feedback wanted)

[twilrabbit]

So I am building a PC which is going to be EVENTUALLY used for software development as well as a general personal use PC; however, I am initially going to use it to convert/re-download over 2TB of video (lots of small files, not a few large files; about ~100k video files of various formats alone), as well as to convert and edit my 10k song collection of flac's. Time is not too big of an issue, but my dell laptop running an N2840 is just not cutting it; especially when I am also always compressing/decompressing files and running 2 dozen tabs on Chrome.

 

So far my build plan is (owned items are italicized):

-Gigabyte H170n m-itx motherboard

-Corsair 250D case

-2x 2tb WD green drives

-Samsung 850evo 120gb (currently running OS on the laptop)

-16gb DDR4 2133 kingston hyperfuryX

-Intel 600p 256gb (Will be main OS, 850evo ain't cutting it)

-500W silverstone strider bronze modular PSU (settling on silvestone cause I already own modular cable kit PP05E for it)

-GTX 750STRIX (used to game, not much anymore)

 

-Finally, I can't decide whether to doll out the extra $100 for an i5-6400 or stick with an I3-6100 (dilemma here is whether I need the 2 extra cores, the i3 has HT)

budget wise, I can't afford an i7, and the 16gb of ram choice was made since im currently topping 6gb of ram usage on my pc currently

 

tl;dr: If im building a PC strictly for file conversion, compression, storage, compiling, and web browsing (SIMULTANEOUSLY); would I be better of with 4 cores or is i3 with 2(4) cores enough?

How much do you care about speed. the extra core Will make it faster.

Quite a bit, I've almost exclusively had dual core comps for most of my life, aside one or two quad cores, but didn't use em much to make a noticable impact; now that im on the comp all day, im strongly considering it (seeing as the CPU is the most important part for the purposes of this build)

With Intel cpu prices reflect performance differences. 

 

If you are building a machine that will almost exclusively handle de/compression consider an AMD FX cpu. They tend to have much better performance in this area.
