About GTX750ti brand ?

[SamuelSanjaya]

so i want to buy a gtx750ti, and they have different brand like asus, msi, zotac, gigabyte.

is there a different between a gpu brand ? which is the best brand ?

also i see gtx750ti and gtx750ti oc, which is better ?

and one more question, there's two type of the gpu, single fan and dual fan, if i didn't use it for overclocking should i get the single dan or the dual fan ?
my psu is 450w, is that enough ?

sorry that my english is bad, and i ask a lot of question,i'm still a noob to this gpu thing.

Get Zotac 750Ti because of 2+3 year extended warranty.Get the small single fan model because 750Ti doesn't need additional cooling.
450W PSU will be more than enough.
