Well i bought it!
Should be coming in a few weeks
lol asa yeah that would be 2 cards, hence the x2 next to it, but i edited it a bit
And actually i went with the regular lightning that has only 1.5 gb of ram insted of the 3, because for my monitor the max res is 1920 x 1080 and on comparision reviews the xtreme edition only gets about 1 fps more on average
If i had a 2560 x 1600 res monitor then i would see much better fps increase.
Oh, the 580 GTX Lightning is $525.99
and the xtreme is $599.00
