HD 5850 vs HD 4870 X2

I was wondering which is the better card.
In the HD 5*** series review by [/url] ([url=http://www.techpowerup.com/reviews/ATI/Radeon_HD_5870/10.html]) the HD 4870 X2 is usually faster in most games than the 5850:

It is obvious then that the HD 4870 X2 is the faster card, but the HD 5850 also has several advantages:
Direct X 11 is one of the advantages you have all thought of. However, the only game that supports Direct X 11 at this time is Dirt 2, and it has been announced that direct X 10/10.1 cards can use the main features of Direct X 11 via a driver update.
However, the HD 5850 is about £40 cheaper than the X2, uses up a lot less power, and is a lot cooler, as far as temperatures are concerned. I will also be able to run two 5850's in crossfire with my 800W (4x12V:20A) PSU, when I would need at least a 1000W PSU to run two HD 4870 X2's.

So, in your opinion, which would be the better buy?

the 5850

Current lcd's refresh at 60 Hz ... that means 60 fps on the screen NO MATTER HOW MANY FRAMES YOUR GFX CARD IS PUMPING OUT

the 5850 has tricks the 4870 x2 can only dream of , and it saves masses on power too

Look at the graphs I have inserted. The HD 4870 is completely dwarfed by the 4870 X2 and the 5850 as far as performance goes.

OK, HD 5850 it is then, thanks

I would definatly go for the new generation 5850! Im thinking of buying the 5870 but im not sure if it's worth the extra £100.

Nvidia will be responding to the ATI release anytime soon but I know that whatever they release is going cost a arm and a leg! So im going to go ATI for the first time!
