Which is better Zotac Gtx560ti Amp! or Msi n560gtx-ti twin frozr ii 2gb or Msi n560gtx-ti Hawk ?

Please tell me which is better and why. Actually i am looking for this cards mainly for doing works like 3d modelling, sculpting in Autodesk Maya, Mudbox. I would also like to play the latest games that uses the physx feature of Nvidia. My budget is Rs. 13,000( INR ).Thanks.|||HAWK is the best OCing series of MSi. You should consider that. But as 2GB version of TwinFrozr is available, so you should get that. 2GB will definitely help you more in ur work. If MSi 2GB isnt available, then you can get 2GB versions from Asus if any. If Asus 2GB version isnt available then your ultimate choice is the Zotac 2GB version.|||The Hawk any day. It has more clock and past experience has proven that the HAWKs from MSI overclock like hell.
