is the 4850x2 a 1gb or 2gb? they made both. if its 1gb get the 4890 if its 2, then it depends on rez, your psu, etc.

by real, 4850 x2 card on crossfire..are better.but after put 2 GPU on a card,it perform 15%-20% less performances then 4850 on CF.
4890 is a really outstanding card..performs very well..+ ur res is 1680x1050. 4890 is better choice for that

Umm No..

4850X2 is a tad slower then a 5850. Get the X2. You'll regret the 4890.

Why would you even bring up Xfire? The gpu's are on one card

The X2 runs really cool as well. You might lose HDD bays in your case, but who needs all of them?

one core vs two does not matter and the 4850xs does not get hot so you will not have to worry about it...the 4850x2 is a better card it preforms better but what kind is each card? but the 4850x2 out performs the 4890

just without DX11
who says this?? I do not believe that at all... the 5830 can over clock to a 5850 stock bud. they think the 5830 has the same chip as the 5850 just underclocked...

4850X2. 5850 performance costing $100 less(than 5850) and without directx11.

Also 1g or 2g dont matter on performance if you are not playing very high res.

I would go with the 4890, the 4850x2 will suffer from lack of support just like the 2x's 4850's, so some games will scale well while others will have the performance of a single 4850, so honestly unless you check the reviews and see what games it scales best in, and those are the majority of games you are going to play. While the 4890 will be the same performance all around (aside from performance differences from game engines).

edit: also the 4850x2 is sapphires' design so you have to deal with their tweaked drivers. That was a big reason why I personally had no interest in it.
