First time build! Help appreciated!

[Icte]

Hey guys!

First post ever! Anyway a short intro (skip if you'd like but will give you more insight into my problem):

I've never built a PC in my life, but for the past 1.5 years I've been looking up everything there is about computers as a hobby online and I've learned A LOT. Some of the information I actually got from this forum and I thank you for it!
Now, I'm almost a graduated electrical engineer located in Sweden and I do program quite a lot. I love gaming and will be moving from PS3 & XBOX 360 to desktop because it's just awesome! School has also made me do a lot of CAD working and I most likely will continue with this.

Now to the problem - the CPU. I will tell you immediately that the crappy TIM used in Ivy Bridge and Haswell has turned me away completely from them as I do not want to delid. I love fluxless solder and will always love fluxless solder and nothing can ever stop me from getting a CPU with fluxless solder!
This leads to the obvious choices between Sandy Bridge, Sandy Bridge-E and Ivy Bridge-E. Since I'll do a lot of CAD and do want a future-proof gaming machine (the new consoles will use 8-core CPU's) I'll need as many cores as possible, and the 6-core CPU's are what I want. Hence, no Sandy Bridge.

Over the past month I've been having my eye on the older i7-9xxX models. I'm on a tight budget and saving as much money as possible would be best for me (poor student alert).

With this information, I leave to you the CPU's that interest me most: i7-980X, i7-990X, i7-3930K and i7-4930K.

i7-4930K just recently came out and is expensive for my taste. I know, 6-core CPU's are expensive and I pay for premium but no. i7-3930K is still expensive (the "cheapest" I saw was one for £350 on eBay).
I've seen a couple of used i7-980X's that have been sold for same price as a i5-4670K, sometimes even lower. These do interest me but are they future-proof enough?

So, in summary - Will a used i7-980X be future-proof for another, say 5 years? I do plan on using SSD and upgrading graphics cards until the point where the CPU bottlenecks them (SLI is also possibru). I know that i7-3930k >> i7-980X in everything and that LGA1366 is outdated but the price and the reliability of the processor is just so tempting..

I would move to a good 2600K-2700K and overclock it to the sky.. At 4.8GHZ you will be rocking for a very long time, for nothing in the world i would pick a 980X at this times, when the i7 2700K crush it in almost any activity, with a 980X you will get few seconds faster on fully multi threads applications.. But in the rest a 2700K will be much better specially at more than 4.5GHZ.... But the thing its if you wanna do a better deal, wait few days until the 4930K take more time in the market, the 3930K will be easy to find in cheap prices..... But taking a decission now, id stick with a highly OC'd 2600K/2700K..

Buh I need more cores.. You know, for CAD and stuff?

Yes i know, i work with those kind programs, also with other kind of stuff, and no.. You no need a i7 980X/990X compared a 2600K/2700K... Yo no need the extra cores as you have 8 threads thats are way far enough for CAD.. As i said you could render few seconds faster with a 980X/990X. Few seconds, just that.. What took 50secs on 980X take 60secs on 2600K.. But in the rest of the things the 2600K will be much better than 980X specially if you will move to dedicated PC gaming.. If you wanna move to six cores over a 2600K/2700K then you only can think on 3930K..

I would not consider a 1366 system.

I do work for an architect. Last year we built him a 3770k system and it works great for him. I wouldn't shy away from a Haswell like you are, just get a 4770k and put a good cooler on it unless you want to spend lots and get the 4930K.
