Im currently running on a APU and I'm thinking of upgrading my graphics now. I've chosen the R9 270X series of cards but the ones I'm interested are the Gigabyte Windforce 3x R9 270X and the Sapphire Vapor-X R9 270X. They both say the heatsinks are great but I'm getting 50/50. Which I'm pretty sure there will be only 1-2 fps difference due to the cards having the same chip but I was wondering which one runs cooler and quieter. My case is a NZXT Phantom 410 which can fit both of those cards. Here are the graphic cards:
