Reddit mentions of CORE I5-4590 3.30GHZ

Depends on your budget. You can get the i5-4590

• refurbished at Newegg for $130 (https://www.newegg.com/Product/Product.aspx?Item=9SIA77G7VX6459)
  
  
• used on Amazon starting at $115 (https://www.amazon.com/gp/offer-listing/B00K5J22GG/?ie=UTF8&qid=1541691577&condition=used).
  
  
• $90 on ebay? (https://www.ebay.com/itm/Intel-SR1QJ-Core-i5-4590-Quad-Core-3-3GHz-6M-5GT-s-DMI-LGA1150-84W-Processor-CPU/372485871928?epid=27016498061&hash=item56b9e35938:rk:1:pf:0)
  
  which I think isn't too expensive and you'll get what you're used to playing with. Any less and you really start compromising in performance. If I were you I would buy on Amazon and find a seller that has positive reviews specifically about CPUs.

That is a good build. But you can improve it a bit.

The i5-4690 does not need an aftermarket cpu cooler, the stock cooler is nice and quiet. 100€ for a H97 mainboard is a lot. Does the mainboard have something you need? 16GB is more than currently needed for games, and you don't need a 700W psu for that build. Also, the case should come with those fans.

This is what I'd get:

Note that this also uses a psu with a lots of watt, but this is because of the usage of the R9 390, which is a bit faster than the GTX 970 and has more Vram. You could just switch the case with the Silent Base 800 and be done.

Ok, so if I were to replace the Mobo, GPU and CPU with the below, would that fit in with the components I already have?

Are these good choices?

I looked on Amazon, cause i don't know any greek shops. This is probably the best performance per Euro you can get.

I have the same Cpu on the 1155 platform and though you can't oc it, it's a beast.

If you need an overclocker.

Thanks, so I would need something like this if I went with the 4590 and the haswell?

I'd recommend comparing the 4590 with the 4690K:
http://cpuboss.com/cpus/Intel-Core-i5-4690K-vs-Intel-Core-i5-4590

For a small amount of money more you can get higher specs:

4690K

And yes, for your build you will only need, approximately, a 400W power supply as your build roughly needs 326W of power, but I'd say possibly go for a 450W or 500W PSU, incase you want to overclock/upgrade in the future.

And so save further upgrades on the PSU get a Gold Certified, or higher, and get it fully modular, not Semi-modular, if you can afford it. It will keep your case cooler having less wired, and it will look nicer, if youre into that sort of thing.

Also for the GPU, if you do get the parts you have listed, maybe splash out a extra 100 dollars on the graphics card and get a MSI Nvidia GTX 970 4GB, its amazing and your system wont be 'bottlenecked'. (Not sure how to use that word in context correctly.

MSI GTX 970:

Also, do not just buy a SSD, you will need a HDD aswel, I'd recommend only using your SSD for your OS, and other programs you use all the time and would like to preform faster. Your SSD will become very slow quickly otherwise, and need replacing frequently (I have found any ways!)

These are all my opinions btw, its not fact, just opinion.

Also, keep in mind you have a Mini ITS and a mini tower, make sure all of your parts will fit in there before purchasing
