Coding server, change, please help me.

I use this configuration, (video encoding) but it's slow, very slow …

Intel Xeon E3-1240 Quad-Core, RAM: 24GB, 2x HDD of 2000GB, Bandwidth: 1Gbps without measuring – 48 € / month

I want to change

Intel® Core ™ i7-6700 Quad-Core, 64 GB of DDR4 RAM, NVMe SSD 2 x 512 GB, 1GBit / s-Port without meter – 42 € / month
Intel® Core ™ i7-8700 Hexa-Core, 64 GB of DDR4 RAM, NVMe SSD 2 x 1 TB, 1GBit / s-Port without meter – € 67 / month
Intel® Core ™ i9-9900K Octa-Core, 64 GB of DDR4 RAM, NVMe SSD 2 x 1 TB, 1GBit / s-Port without meter – € 80 / month
+ € 80 configuration

Will I have better times, with the latest configurations?
