I have now 1xati 4890 card.(directx 10.1) If I install a 5870 card (directx11) Can i use crossfire with the old card? More about : crossfire Maziar a c 169 U Graphics card January 6, 2010 8:41:15 AM No,the cards have to be the same (or from same family for ATI cards) So you can CrossFire a HD 4890 with 4850,4870,4890,4870X2 but you can't CrossFire it with a HD 5870 m 0 l wa1 a c 189 U Graphics card January 6, 2010 8:58:35 AM If u already have 4890, i would say u better stay with that card for a while, since there's only some games that support dx11, your card is already the "beast"... U can buy HD 5XXX series later. BTW, just like Maz said, you cannot CF 4890 with 5870. m 0 l Related resources Need help with adding 290 crossfire into my system. - Forum Crossfire help, please! - Forum Crossfire urgent help requested - Forum MSI R9 290 Crossfire help - reaching 94C within minutes - Forum R9 270x crossfire with 270 mass of screen tearing and mix of pink colors help plz - Forum Can't find your answer ?

The compelling reason to get a DX11 card is if you are to purchase a new one or to do a major upgrade. If money is of no concern yes...5870 is the way to go. If you want a cheaper performance boost get another 4890. A CF 4890 is better than an OC 5870...

PS: Just how much better is running 2x16 PCIE vs 1@x16 and 1@x8 in CF setup. I currently can only use the later. m 0 l Can't find your answer ? Ask !
