Titan Virtual Force i7 vs Chromium i5

[y2_dyc]

Hi all,

I'm looking to buy a pre-built gaming PC by OC with a budget of between £1400-£1600.
I was hoping to get your opinion on the 7th vs 8th Gen Intel chips with virtually the same spec. The Chromium with i5 cofffeelake chip is £300 cheaper. What would you chose between the two specs listed below?

And any alternatives and changes would be welcome.
Thanks for your time

Chromium for sure, end of line for i7 7700k, old tech, only few fps difference vs i7 7700k and and with that £300 saved ,you can upgrade to a better cpu or gpu in few years...

Thanks for your reply! I was hoping i could use the extra £300 for i7 Coffee Lake, but there aren't any pre-built specs within my budget. Is it a matter of waiting for a bit longer to see what OC have to offer? Or would you recommend ordering parts separately and getting OC to build ensure getting their 3 yr warranty.
