Please explain me, i must be satisfied and know that i can buy this card.
Also there is any version of 5870 with 2.0 ? In some sites of shops i see Powercolor 5870 2.1 pcie with the same photos of 2.0 version. But looking into official site of Powercolor i see only 2.1 versions. So?
Video cards complying to any standard are always backward compatible.. Thus your card will work fine with your mobo.. And it'll also work full throttle if you've the right gears.. Rest assured, your mobo will not be a bottleneck in extracting full performance out of your card.. So don't worry.. HAPPY GAMING..
Powercolor is an established brand so i would not doubt them in terms of quality.. The problems might arise for anyone due to mismatching of components ( such as getting an underpowered PSU for a card as powerful as the 5870 ) or it may be pure bad luck.. But if shelling out a few extra bucks give you peace of mind then sure you may go for other brands..
