Hd4890 vs hd5770

[terribleteee]

I just bought two hd4890's for a new build and haven't opened the box's yet now I'm thinking of replacing them with two hd5770's pros and cons the prices seem to be about the same.

4890s outperforms 5770s
(5770 is almost equal to a 4870)

5770s support DX11 and more monitors

so with dual 4890's i'd outperform two 5770's what is the advantages of DX11 though?

As bluescreen said,HD 4890(and 4890 CF)beats HD 5770(and 5770 CF).
The advantage of 5770 is that it supports newer techs like eyefinity and DX11,about DX11 well there isn't a DX11 game which is out yet so you have to wait for a DX11 game to out(such as Dirt2) and check its performance.

when DX11 games start to come out would they be compatable with a card that doesn't support dx11 or do you think they'll issue drivers to fix the problem?

Games are still compatible with DX9. Best guess is developers will drop DX9 in 2 years. DX10 should survive for at least another 2 years after that.

dont buy anything form the 5___ series that is not 58__...the 4890 is a solid card. 2 shoudl just about shake the earth. If you want better you will need to go up to 5870

 

[CRdloader]

O yea....ATI has a bad habit of making unstable drivers when they relice a new card. There is a chance the driver for the 5___ card might be a little shaky while the 48__ drivers are well refined.

I think you should get the 2 4890's
dx 11 has a big chance of being useless just like dx 10
and the performance is way better on the 4890's
