I currently have one of these

Now if I was going to put another one in my system to run in crossfire would it need to be the exact same card or could it be another 4850? i.e.

Many thanks

It can be any other 4850.

Make sure they both have the same memory size though, otherwise the higher memory one will be limited to that of the lower one.

If one has higher clock speeds make sure that is in slot 1 (so that slot 2 card is forced up to those speeds).

i think you should sell the old one and buy 2 new ones

then it will look better as well

Just add another 4850 in, the brand doesn't matter at all.

Selling one for another two sounds a bit drastic

err, they run at independent speeds, you're thinking of sli.

Ah my bad, assumed it was the same for crossfire too.

In that case buy whichever 4850 you like
