Hi there, I live in Brasil, and I bought this 6870 MSI HAWK from USA for 214 dolars about 1,5 month ago. As you may know, the taxes here are awful, and the dolar is very high (1 dolar = R$1,87). So, a 6870 here is worth about R$600. Since I'm going to NY next month, I was thinking of selling my 6870 here, for about 600, then I will have, 320 dolars from it. And I saw that in newegg the 7870 powercollor costs 329 dolars, is it worth to change my videocard? For those who didnt pay atention to the math, I wouldnt spend any money on this, since I'd sell my 6870 here, and this money would be sufficient to buy a 7870 in USA. Is it worth it? The 7870 is really a match for GTX 580? If not for a 7870, for a GTX 570? performance gain on the way?
