Crossfire arrangment

[claigeo2007]

I am looking to purchase two video cards to hook-up in a crossfire arrangment, The XFX HD-577A-ZNFC Radeon HD 5770 at; http://www.newegg.com/Product/Product.aspx?Item=N82E16814150447&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-N82E16814150447 or the XFX HD-489X-ZSFC Radeon HD 4890 at http://www.newegg.com/Product/Product.aspx?Item=N82E16814150438&Tpk=XFX%20Radeon%20HD%204890. I am seeking advice to make this decision. Or would it be more practical to purchase one XFX HD-587A-ZNF9 Radeon HD 5870 for a bit more than the two would cost.

I'm thinking you should get one HD 5870, because I'm considering that to replace my two HD 4870s. Then I could add another when the prices come down. We know the 5870 will be good for long a while.

The 4890 has better performance as does the 260....if keeping the GFX cards for more than 2 years tho, the 5770 might be the better buy for longevity reasons.
