So, at the moment I've got a 4870 which is doing fine for my monitor and games I play. RES: 1280 x 1024

However, sometime this year I'm planning on doing a new build with recycled parts and I was wondering if I'd be better off Crossfiring another 4870 or just buying a 5850?

I'd be glad to hear your opinions on this as always :ange:

Can you post your sys spec?

And the decision whether to Xfire HD 4870's or one HD 5850 will depend on your power supply. 2x4870 in Xfire would be something like hd5870 but it still depends on weather your power supply can handle those 4870's or not

Be sure to check your sys specs and then post back

2x 4870s = 1x 5870 > 5850

You'll need a good ~600-650watt PSU do run 2 4870s in Xfire.

I understand that 2x 4870s is around the performance of a 5870. What I'm wondering the most is if DirectX 11/Power Savings/Future Proofing worth the extra money I will pay for a 5850 for less performance on the Dx10/9 side?

well i'm going to post what i'm planning to upgrade to rather than what I have now, although, I will hold onto the same powersupply

OCZ StealthXStream 700w : http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Antec 300
CPU: Either Phenom II x4 955 or Phenom II x6 (still waiting to see scaling numbers)
4 gbs memory
monitor = 1920x1080


Then a 2x4870 will suit that system very good
Your CPU will handle it ( either the X4 or X6 )
Your Psu will handle it

As for the DX11 thing if you would consider a 5870 vs 2x4870 yes i would say go for 5870
But, there are few games with DX11 out there and developers are still making DX9-DX10-DX10.1 titles ( except for Just Cause 2 - it won't support DX10)

So i'd say go for the HD4870

I meant Just Cause2 won't support DX9 in that post, sorry for the confusion:)
