Those are the two brands i'd go for (BFG and point of view, for a graphics card, herd bad things about EVGA, the cards are ok but the customer service is poor, as their service centre is in germany lol
theres no difference in the cards, theyre all built with the same componants etc the difference in price is warrenty and game bundles with it. so have a look at the type of warrenty offered with the cards and what the reviews say about them, and go from there.
although BFG cards always seem to be more expensive then any other of the rival brands
