i might buy this whole kit or maybe just upgrade my gpu to a gtx 1070, which one is more worth it in ur opinion?

If I got this correct, this set would cost 6200 SEK, which is about 760$. Not sure how prices in Sweden look like, but similar set in US would cost around 530$, lets add 23% VAT that's around 650$. Not worth at all it seems.
GTX 1070, on the other hand, could indeed increase performance of your old system.
