so I am thinking its time for an upgrade after seein all the eye candy new games at E3, first off will a PCI-E 2.1 card work on a 2.0 MOBO? Here is what I am trying to decide on should I get 1 5850 or 2 5770s or is there something better for that price range? also I have an E8400 @ 3.7GHz prolly soon to be closer to 4 but I don't need to worry about bottle necking wit that do I? I don't think so cause it seems to be pretty fast but I just wanna make sure
