So I've been running a 2500k with a max 43 multiplier for years, but got 2 more systems for cheap and wondering if I should make those my primary or swap any parts. Any advice would be greatly appreciated.

Processor

i5 2500k OC max multiplier of 43 (cinebench score - 1200)
i5 4670 (cinebench score - 1360)

The 2500k has a higher clock (when overclocked), but I don't get why the 4670 got a better cinebench score. I feel the 2500k should be my main rig still, but the cinebench score has me doubting that. The results here show an OC'd 2500k is generally better, but it doesn't say what the OC was.

Motherboard

Asus Maximus IV Gene-Z/Gen3
Gigabyte GA-Z68X-UD3H-B3 rev 1.3

I only have one motherboard for the 4670, so that has to stick with that, but I have the above 2 that work with the 2500k. I've been on the Gigabyte board since new and the Asus I just got. I know the Asus is mATX vs the full size Gigabyte, but seems to be the higher end board? Asus usually has a friendlier BIOS? Can't find great info, but he Gigabyte looks to have single phase power and the Asus has 8 phase, so better for OCing?

Graphics

EVGA GeForce GTX 970 4GB
MSI GTX 950 2GB
PNY GTX 760 OC 2GB
EVGA GTX560Ti

The 970 wins by far, so that's going in my main rig, but which card for the second rig? The 950 and 760 seem to be super similar. This comparison seems to have each winning in different areas. Overall it sounds like I should use the 950 for the second rig since it's the newer tech?

Power Supply

Corsair GS800
Seasonic SS-620GM Active PFC F3 (modular but don't have the extra cables)
Seasonic SS-430HB Active PFC F3
Corsair VX550

It's new and not tested by me yet, but seems like the Corsair GS800 should clearly be my main rig. The Seasonic 620W seems to be the best choice for second rig, but it's modular and the owner didn't give me any extra cables. Should I keep the Corsair VX550 for this reason, or is it not a big deal? I think I have enough connections for my basic setups, so maybe the missing cables aren't a big deal?

Case

Fractal Design Arc Midi R2
Lian Li PC-C60
Antec Nine Hundred

I know this is more subjective, but any downsides to a case that make it so I should avoid? I currently have the Nine Hundred as my main case, but the Fractal looks really nice to me, so that's my pick for my main rig. The Lian Li is a horizontal HTPC type case, but is my pick for secondary rig. I do like the Antec and it's the one I've been using, but the other 2 seem to be better overall.
