Crossfire 2 non-identical cards

post #1 of 19
Thread Starter 
Hey guys, been thinking about putting my 4870 in crossfire with another one, but i can't any on ebay or anywhere that are the same make, Asus 4870 512mb.

So my question. Would I be able to crossfire my Asus card with any other 4870s? or would i need to get the exact same card?

Thanks in advance

Any 4870 would would, not just an Asus one. You should try and look for another 512MB one as well.

Yes they will crossfire, but if one is faster than the other, both will run at the speed of the slower one.

I'd recommend you upgrade to a 5870 or a 6870. They are the best bang for buck cards and at least TWICE as fast as your current card. You'll get horrible scaling in X-fire with 4870's as well.

Maybe for the next upgrade, but 4870s are going really cheap and I've never crossfired any cards before.

you are better off getting a new gpu instead of crossfire older cards like your 4870.

Yes of course you can overclock them.

Just make sure to keep them at the same clocks, because you don't want to be paying for the extra heat/energy they put out/take in.
