I'd get the cheaper of the two.
MSI is cheaper by 4 euros!!! lol!!!
@IcY18: I have space in my case/mobo for a dual slot. The only other card that is connected is a Audigy sound card (yep the original). So I don't mind at all.
I gave the manufacturers links so more people (that know more than me) can confirm that they are identical except the cooling solution.
