Sandy Bridge to Haswell - worth it?

I have been running a i5-2500k for the last 2 years and it has been a great processor. However recently the motherboard (MSI Z68S-G43) has starting whining and acting odd with disconnecting drives. I was going to replace it with an Asrock Extreme4 Z77 motherboard and still might but I thought, would it be worth while upgrading to haswell (i5-4690k) instead of replacing an old motherboard?. What performance increase would there be if any? Is it worth spending the ~£260 instead of £90 for a new old Z77 motherboard?

From a gaming stand point, i moved from a 2600k to a 4670k and could not tell the difference. It could have been the move from the 580 to 980 and 1600MHz to 2133Mhz ram at the same time that is overshadowing an improvements that i could have seen with the cpu.

In theory a move from a gen 2 to gen 4 should net you about 20% gain. But like others have said above, if your going to buy a new board might as well buy the latest socket. A 4690k should last you good 3-5 years at least where the 2500k is in the middle of its life and coming to its end.

Honestly, the difference between the i5-2500k and i5-4690k is not very big, and you're not going to notice much of a performance increase, if it all:

However, if you are going to replace your motherboard anyway, then it makes sense to upgrade. I would let it depend on what you do with your current CPU. If you can sell it and recoup some of the costs of going with a newer CPU then it make sense to do so. If you're just going to throw it away, then imho the price difference is too much.

I have the same mobo paired with an Ivy Bridge 3570k and I plan on riding this for at least another couple years. You won't notice a huge bump in performance upgrading to a haswell. Either buy a P67 or Z68 mobo and drop the i5-2500k in there or do a complete upgrade with a new mobo/cpu.

Depends on how much of your hardware you want to keep/change. Z97 is going to be the last gasp of the true DDR3 motherboards from Intel and it doesn't have SATA Express, but you can get M.2 for speedy SSDs.

(Not sure on Skylake, roadmap lists both DDR3 and DDR4, so perhaps LDDR3 for mobile and DDR4 for desktop)

Of course that is more then a year out, and closer to 2 years out, most likely.

Thanks for advice. Although I wouldn't be selling my i5-2500k, I would give it to my mom, completely over kill for what she uses here computer for but she is currently use on a Core 2 Duo which is very slow and has wanted an upgrade for ages. Since she is using DDR2 RAM , I would have to buy more RAM anyway. I was wondering (instead of starting a new thread), would it be worth while buying 1866MHz RAM (currently using 1333MHz) for gaming? Or sticking to 1333MHz. I currently use my computer for gaming, programming, word processing and potentially getting into 3D modelling (Blender)? Overall, would it be worth while getting an 4690k and 1866MHz RAM for my needs?

If he just replaces his mobo with a new one, the i5 2500k would not work...just keep what you have unless the problem is the hardware, ram speed does not affect gaming performance by very much at all.

His motherboard is failing. He wants to replace it with another board of the same chipset.....

He is asking if he should make the move to Haswell which would involve replacing his motherboard and the CPU. I recommended he simply replace his existing motherboard and leave it at that.

OK thanks for your help everyone. Think from all that I will just replace the motherboard which I have now with a Asrock Extreme4 (think its the best one still available in the UK?) instead of purchasing a new CPU when there isnt much performance gain from spending that much money

Long ago ASRock was the bargain brand of ASUS. They split off and still make budget parts, but of good quality. They also have their extreme series which is competitive with all the major brands.
