It should be compatible. However, it's unlikely to actually be any faster than the 6670.
Thanx Someone Somewhere
I know that speed will be more or less same
I have to Replace it because I had brought AMD Radeon R6670 MD1GD5 - 1 GB DDR5 from one of my friend for testing but now I have to return it and there is no availity of that card in market
And a graphics card retailer suggest me AMD Radeon R7 240 1GB DDR5 or R7 240 2GB DDR3
That's why I am asking!
then will it be ok to buy AMD Radeon R7 240 1GB DDR5 or R7 240 2GB DDR3?
