What are the issues of buying 4th Gen CPUs?

[Syvered]

I currently have 16GB of DDR3 RAM I got for free and I was thinking I should but a i5 4590 instead of i5 7400 and a H81M-E34 motherboard instead of B250M BAZOOKA. This way I wouldnt need to buy 8GB of RAM which costs 60 euro to the i5 7400 route. So I would get a CPU with the same performance and 16GB RAM for cheaper than i5 7400 8gb RAM. SHOULD I DO IT?

In all honesty, I would buy the i5-7400 with 8GB of DDR4 RAM since it will be much faster and you can buy 8GB of RAM in the future whereas if you purchase an i5-4590 with 16GB RAM you will have a slower CPU and slower RAM and if you were to upgrade you would need to buy a brand new motherboard and an i5-7400 and 8GB of DDR4 RAM.

well ive been thinking about the same thing. But the old gen isn't very future proofed for compatibility, so you're going to have to upgrade sooner rather than later.
ive decided to go for new gen btw

That's a good choice, the new gen is more future proof so you did the correct decision

The i5 4590 is NOT slower than the i5 7400.

The i5 4590 is NOT slower than the i5 7400.

The i5-4590 is NOT better or more futureproof than the i5-7400. The i5-7400 It is better as well lmao, what you talking about?

 

[Syvered]

They have same performance... The i5 4590 is even more expensive than the i5 7400...

There's absolutely nothing about the kabylake cpus that's anything to do with any application of being 'future-proof'. It's a dead end. A year ago, if you were looking at lga1151, it had some future-proof, owning skylake and had the possibility of moving to kabylake when it was released, but with kabylake out now, it's done. The only thing that'll be future-proof is anything not core related, such as the ddr4, the SSD, possibly the cpu cooler, but the cpu/mobo is done. Dead end.

And I'll put my i7-3770K up against your i5-4590 or even the i5-7400 anyday and still beat you in any bench. Age isn't the primary concern with cpus of Ivy or newer as much as the model, power and ability.

Yes, a 'new' 4th gen cpu is more expensive than a 'new' 7th gen, but that's how supply/demand goes. I built my entire pc for less than $600 few years back, when the generation gap was smaller, but it's still strong enough to handle whatever I need from it today.
And there's plenty of still perfectly good 4th gen cpus/mobo's on ebay at much lower prices than retail new, even some 4590's brand new in box for $95. Kinda hard to beat that.

Y'all arent understanding what Im asking... I probably didnt ask it the right way, here I go trying to explain again:

An i5 7400 with B250M BAZOOKA and 8GB DDR4 RAM costs 319 Euros.
An i5 4590 with H81M-E34 (and no RAM because I ALREADY HAVE 16GB <- THIS IS THE MAIN PROBLEM costs 261 euros.

So basically I'd get SLIGTHLY WORSE performance for 58 euros less and 8GB more RAM!

Not really. The 4590 is slightly stronger than the 7400, mostly due to the 4590's higher clock speed making up for the kabys higher IPC.
The B250M is a better board than the H81, has more available options, will have longer lasting support and updates.
DDR4 is faster than DDR3 and has better bandwidth, so even 8Gb will be less of an impact on the system as a whole. Granted 16Gb of even slightly slower ram will be better than 8Gb of slightly faster ram.

So, this is what you are looking at.
4590- win / 7400-loose
H81-loose / B250-win
DDR3- FREE! win-win! / DDR4- loose
Cheaper- win / More expensive-loose
Short support- loose / Long support- win

You'll get better overall performance from the 4590 build than the 7400, since they are so close in comparable ability, they'll last equitably long before needing upgrade, not because of age, but because they simply aren't powerful enough to really keep up with your demands. That could happen in 6 months.
The only real issue I see is the choice in mobo's, that H81 is junk compared to the B250 Bazooka, something like the ASRock H97 Anniversary is just a few euros more, but a better board, with much better options and much better LAN capability.
