i have two card one is asus en 210 and aonther is asus radeon hd 7850 can i use both card to gain some more fps in game...though i know they are two different vendor card i cannot do crossfire or sli.....is there any way to do it....?
In general No. SLI requires 2 Nvidia cards and Crossfire requires 2 AMD cards. There are as said specific rules that govern which two cards can be used in tandem as well.
You can get motherboards and indeed special cards that have a chip on them from Lucid, that allow cards from Nvidia and AMD to work together but its not something I have any personal experience with.
That board does not have the chip, that board is Crossfire only capable. If it had the chip it would be pretty obvious, as you can see in the picture that is in the link I posted its quite large, its about the size of a second CPU.
