crossfire or new graphics card?

[csou]

Thank you very much for your time. I appreciate it! My pc case is this
CASE COOLERMASTER RC690 PURE BLACK. I really don't know if the graphics card you mention could fit there but I will go to pc store and ask about it. I will probably purchase my new card from there and what the heck, they will know the answer to the problem. Your solution seems quite logical to me, but to be honest i purchased the graphics card in July and it is quite inconvenient for me to change it in less than a year! Anyhow see the specs of my pc case and if you have a further comment, please write it down.
