Old GPU (GTS 450) vs New Integrated GPU (Intel UHD 630 I5 - 8600k)

[juanfri.warfare]

Hi everyone,
So im building a new PC at the moment but im on a budget and can't buy everthing together, so i've bought an i5 8600k with an asus z370-F Gaming and 16Gbs of G.Skill Trinddent Z 3200Mhz RAM. but no new GPU and my OLD one is a Gigabyte GTS 450 1Gb DDR5. And i was wondering what i should use will i wait to get my new GPU. Should I plug in the 450GTS or leave it out and use the integrated one? Thanks for the help!

The 450 has a furmark score of 2308 the built in graphics is 1270 so the 450 is about 2x better.
