GPU & Shipping

[♪~ ᕕ(ᐛ)ᕗ]

Alright so I'm looking to buy a new GPU ($100 max) and I've seen some pretty basic stuff like GTX 650, 550 Ti & 750. But here's a problem:
During some of my researches about which one should I buy, I've found some sources saying that 550 Ti is better than 650 which itself is better than 750. What? Some other sources came with benchmarks showing a big advantage of the 650 over the 550 Ti.

In other words which one should I go for?? (550 Ti is kinda hard to be found in the internet [from a reliable source])

Also does newegg ship worldwide? If yes then can somebody link me to a page where I can read the policy?
EDIT: Nvm, https://kb.newegg.com/FAQ/Article/1400 Can you recommend me another website to buy the card (not amazon or ebay, I already know them)

get a 750ti, its better than both of them and has low power consumption.

I have a GTX 750Ti OC 2GB and it works just fine
