creating a crossfire setup

[Jobe]

hey guys.
i have a his x1900xt and want to go crossfire. i know i need a crossfire mastercard.
is it right i can use any brand x1900xt or does it need to be a HIS?
i know i need the crossfire cable which i think i can get.

thanks in advance.

depends if you want crossfire for the sake of having 2 cards or you want more performance. Would make more sense to just run a single 3850

Seconded, you can get a 3850 512MB for around £110, so you'd be best off getting one of those. You might find it difficult to find a 1900 master card for crossfire

can get a master card for £70 inc so for £40 can get a 3850. will one of these be much better than xfire x1900's?

A 3850 512MB should be roughly twice as fast as an x1900s card

.....and i'm sure you get £40 for the x1900

in crossfire tho?

also is there a decent site that has comparable benchmarks for many differing cards

X1950 Crossfire should be roughly the same speed as a 3850(with a bit of overclocking) in games that support crossfire properly

the 3850 will be more consistant though. With crossfire you will probably find some games that only gain a small % increase. Another factor is that a single 3850 probably uses about 1/3 of the power that 2 x1900xt's will use
