I wanna make sure that a MSI NVIDIA GeForce GTX 760 OC 2GB GDDR5 will fit in the case im thinking of getting. The case is a NZXT Guardian Black SECC Steel Chassis ATX Mid Tower Case 921RB. And the mobo is a Z87-G41 PC MATE if that helps.
The MSI card is slightly overclocked more, so out the box it might have a minor advantage over the ASUS. But nothing you can't do yourself, otherwise, performance is the same. Note, it uses a single 8 pin, instead of dual 6 pin.
Here are a compilation of reviews to check it out:
