Upgrade help please

Looking to upgrade my kids PC which I handed on to them a couple of years ago. Q6600, Abit IP35, 4GB RAM, HD6870, Corsair HX 620W and a 1280x1024 monitor. It's struggling with games recently now they're old enough to play some of the more graphically demanding titles.

I did think of upgrading my PC which is a i7 4770k, R9 280X, and passing some components on but it still feels plenty fast so I think I'd rather keep it as is.

So... was thinking to upgrade the mobo, processor and RAM in the kids PC with either:

My basket at Overclockers UK:

• 1 x Intel Core i5-6400 2.70GHz (Skylake) Socket LGA1151 Processor - Retail= £139.99
• 1 x MSI H170 Gaming M3 Intel H170 (Socket H170) DDR4 ATX Motherboard= £88.99
• 1 x Avexir Core Red Series 8GB (2x4GB) DDR4 PC4-19200C16 2400MHz Dual Channel Kit (AVD4UZ124001604G-2CIR= £38.99

Total: £278.47
(includes shipping: £10.50)
​

​

Is that right picking DDR4 memory??

or..........

My basket at Overclockers UK:

• 1 x Gigabyte Z97X-SLI - Devils Canyon Core i5 4690K Bundle **£12 Saving**= £257.98
• 1 x Avexir Core Blue Series 8GB (2x4GB) DDR3 PC3-12800C11 1600MHz Dual Channel Memory Kit (AVD3U16001104= £35.99

Total: £305.07
(includes shipping: £11.10)
​

I was going to try and persevere with the HD6870 as it's only driving a small monitor but if I wanted to add a graphics card for around £150 what gets the vote at the moment.

Thanks all.

Thanks for the advice. I wondered if there may be some hidden advantages going for newer tech (Skylake) over the older socket? More 'future-proofed' although I know there's no such thing as future-proofing PC purchases!
