hi im looking for a new gpu and those 3 are the only choices i have because i can find a used card for those 3 and the price are almost the same. ill be playing LoL, crysis 3 ,2,1 Bf 3,2,1 Skyrim. im just an average gamer so i would just want a decent frame rate on very high to ultra settings. and im only going to play at 1366x768p. and will an fx 4300 bottleneck them. thanks

The two HD 5850's are the fastest of the three.
Their performance lies somewhere along the ranks of the HD 7950/ GTX 760.
Two HD 5850's are basicly tied with the HD 5970, which is a bit faster than the GTX 580, which is a bit slower than the HD 7950.
Just make sure your power supply has 4 6 pin connectors (6+2 pin will also work).

I did not understand what you were trying to say, but you can use Molex connectors to power the second card.
It will work without a hitch as long as your power supply is good enough.
If your power supply is a no-brand unit, don't even try .
Also check the number of 12V lanes it has and their amperage.
If it has a single 12V lane, you can connect your graphics cards wherever you like.
If it has multiple, weak 12V rails make sure the graphics cards are not connected to the same power lane.
Otherwise things are bound to go wrong.
What I mean by a weak lane is a lane that can not deliver enough power to support two big components (CPU + GPU, GPU + GPU).
Basicly, make sure that if both of your GPU's are using a single lane, it has more than 37 amps of power.
