Crossfire...Is it possible?

[JDSalin]

Okay so last year around November I built my computer. My graphics card is HIS ATI radeon 4890. I would like to crossfire with a HIS ATI Radeon 5850.

Is this possible? Do both cards have to be the same?

Okay I just checked the HIS site and I see the 5970. Same question as above but this card instead.

You must crossfire with the same card. That means you have 1 option. The 4890.

It would probably be worth more to just replace the single card with one of the 5xxx series.

Damn. That sucks. I guess I'll hold out for a little while longer.

Sometimes you can CF cards from the same series, but it's never practical. They need to be matched.

I just checked on Newegg and the 4890 isn't even in stock anymore so I wouldn't even be able to do that.

There are two 4890's currently listed on newegg.

both cards has to be similar and relatively close in performance

like 4890 with 4870/4870x2/4890
