pls answer, tomorrow i must decide will i buy it or not. as i said, i've heard that certain people have problems with these cards. on the other hand, i've heard that this is very very good card (this particular card that i want to buy works on 580/1500). the problem is that this card is bought in other country, it's new, but it's difficult to get a warranty if something goes wrong. but i have a test period to try it, is it possible to conclude is the card good or not just after maybe one hour of testing? i will try it with 3dmark, some games... and if it all works fine, does it mean that this card is "safe" to buy? can i be sure that card won't make me troubles after just one hour of testing?
