dude... $420 a hit seems a bit expensive for my liking... selling both of those 260s you'd only get enough for one and a bit 280s... and you wont get much performance out of that bit! lol
plenty of people here in us selling 280's for 300 dollars... i passed up 2 chances now for 300 dollar gtx280's... i don't know why!! but next time i am hoping on it
i'm sure dual 280's should yield me something like 40fps being my lowest frames in crysis.. now that would be a dream come true!!!
