Different design between two GTX 970s?

[Kallakix2015]

I looked at a PC that's about two years old, it has 2 GTX 970s in SLI and for the first time I noticed they're built differently. One has a large grey bar near the ports and one is slimmed down and has no bar + some of the wiring is in a different position.

They're both GTX 970 MSI 4GB. What could this design difference mean? Is one an original and one updated, is the speeds effected by this?

Wondering because I was wanting to sell one of them and I'd choose to sell the slower model if that's an option.

If they are both exactly the same (bare in mind their are different MSI models for the 970) then will be hardly any difference between them.

We'd need to know the exact model of each. There should be a product sticker on top of the circuit board of each card to get a model number off of. But yeah like the other guy said, it's probably very little speed difference between the two. But there's no way to know which model the second picture link is.

The first one from NewEgg is the GAMING 4G which runs at (boost / base clock):

1279 MHz / 1140 MHz (OC Mode)
1253 MHz / 1114 MHz (Gaming Mode)
1178 MHz / 1051 MHz (Silent Mode)

I ran both GPUs through geekbench 3 times a piece. The one with the black metal had an average score of 106,439. The thinner silver GPU scored an average of 105,715. I guess they're slightly different in one way or another. I looked for info on the cards themselves and all they said was GTX 970 GAMING 4G on either one.
