i asked the question on facebook and they said that the best way to get an answer is here =)
i have the asus eah4890 card. when i bought it it was really good and powerful card but now with the DX 11 it downgrades my lovely card. i want to buy a new card for crossfire, will it work if i'll buy a DX 11 supporting card
(an asus card)?
my specs are:
AMD phenom II x4 965 3.4Ghz
2x2 DDRII ceon 800Mhz RAM
550 WT HEC
WD 500GB (32MB) SATA II
to successfully crossfire with asus eah4890 you need another 48xx series gfx card e.g. another 4890(preferably the exact model you have). gfx cards from seperate groups cannot be used together in crossfire.
so i understand that the only option for me is to upgrate to another graphic card.
Gman i can't upgrate to Nvidia 'cuz the m.board is not supporting the Nvidia cards. the budget is not important 'cuz the question was if i can make a crossfire with anothe graphic card to run the DX 11, and as de5 posted it's impossible.
thanks guys... so anyway i'll look for a $300 v.card.
Nonstopa.. I can guarantee you that your motherboard does support Nvidia cards. What it may not support is Nvidia SLI (two cards), which is something that was recently added to more modern motherboards, but any motherboard out there can support any single card.
As for your original question, de5_roy is correct in that you can only Xfire with another HD 4890 card, and even if you do that, you still wouldn't be able to run DX11 cause the cards don't support it.
Before you go buying a $300 video card, please let us know the specs of your system so we can give you a better recomendation. What is your motherboard? your CPU? your Power supplu make/model and wattage? and what is the resolution that you are playing on?
Chances are if that's the card you were running before, you won't be able to run a $300 card from your system.
