I currently have 3 desktops. One of them is in dire need of a GPU upgrade and one will be replaced completely. Thanks to help I got here I have my mind mostly set on what I want for them. I just got a message from a friend that offering some other GPUs though. Partlists are not complete, I did not include RAM and motherboards.

For this computer I have a GTX 780 ti to replace the GPU (perhaps a little overkill, but it's basically a gift, so no complaints).

This one does not exist yet. Thunderball made this list for me:
CPU: Intel Pentium G3258 € 72,90
Motherboard: MSI H81M-P3 € 43,90
RAM: Kingston HyperX Savage - DDR3 € 37,90
GPU: MSI N750Ti 2GD5/OCV1 € 117,90
PSU: Corsair Builder Series CX430 € 48,90
SSD: OCZ Trion 150 120GB € 52,90
Total: € 374.4
I'm able to get a GTX 770 off a friend for this instead. He has both the 2gb one and the 4gb one, but I'm almost certain the 2gb one will be fine. The PC is only for playing minecraft and office work. The PSU advised is not going to cut it, though. Thunderball advised me a 620W one instead.
How can I make the best of this?
TL;DR
Desktop 1: i5-6600k + GTX 970
Desktop 2: i3-4170 + GTX 780 ti
Desktop 3 (not bought yet): Pentium G3258 + GTX 770 (or should I get another i3-4170 for this?)
750W PSU
520W PSU
I own all PCs and can interchange parts between them. How can I make the best of this?
