You can but the 4890 will "disable" parts of itself to become a 4870.

is it worth it running 4890+4870 or should i just sell y 4870 ( give it away) and just keep using a single 4890?
post #10 of 14
well 4870 CF will be faster than a single 4890, but than 1GB of VRAM might give you some issues at 1080p
