The Windforce one has 4gb which is good if you are using anything above 1920x1080. The other ones also come 4gb versions though. I think the EVGA one is Quieter though. The MSI one is clocked higher. If you aren't going to overclock the MSI will have a minuscule amount of extra performance than the other two (Not really noticable). They are all good cards and will all perform nearly the same. I would say to get the one that you think looks the best really.
