I have some questions that i really can't find much of the answer by researching.
Originally my plan is to get the Sapphire vapor-X Ghz edition.
And run 2 way Crossfire over 3 screens, 5670x1080.
1>I would like to ask if anybody know the noise level on the Sapphire Vapor-X 7970ghz ? Would it be really noisy?
Also i have the Sapphire 7950 vapor-x come across to me £100($160) cheaper each, so £200 cheaper by two cards
2> Would 7950 in Crossfire be enough to run 3 1080p monitor?? how many percentage lost in performance compare to the 7970?
3> After the driver update, how is the 7950 compare to the gtx 670??
4> I have heard in Crossfire, overclocking cannot go as far as a single card could and is not much of performance increase, I wonder if this is true? If it is, am I better off getting a pair of Sapphire OC boost for £30 cheaper each?
5> i have heard the Asus directcu ii top is one of the quietest 7970 out there and also works so well with the mobo i have, the rampage iv extreme. But it is £20 more expensive than the sapphire ghz.
Which would you recommend ?
7970 Sapphire vapor-x ghz ?
7970 Sapphire OC boost ? (30 cheaper per card)
7970 Asus Direct cu 2 ? (20 more per card)
7950 Sapphire vapor-x ? (100 cheaper)
Any comment or thoughts would be appreciated!
