so 2 260gtxs are about the same as 1 4870x2? And the price of 1 4870x2 will definitely drop over the next 6 months so picking up 1 more in july would be pretty cheap and that would yield better performance than 3 260s.
and i doubt i would ever get 3 280s (could use that to pick up a really nice monitor)
so now all I need to do is figure out which motherboard to get - The Gigabyte UD5 or the MSI Eclipse. Or any other mobo if someone here has a suggestion.
