I have Sapphire hd3870 now, and i'm wondering if i cen crossfire it with nev 3870x2 and is it worth to crossfire it with x2 or i sould simply just buy another hd3870? I think i'll buy x2.....
I would suggest just buying another 3870... since you'll have to sell your current 3870 if you want an X2 which would be just as fast as 2 3870s... so, yeah.
it depends on your motherboard though. if you're currently on a p35 or p965 or something without 2 full 16x pci express slots, it would be much better to have a 3870x2, since it wouldn't be bottlenecked by the bus speeds. i currently am running crossfire on a p965 board, and when it works, it works great, but there are some games where it doesn't work very well at all. so just something to keep in mind. i'm in the process of upgrading to an x38 board so i can have full bandwidth.
