Our Score:


All our testing uses a variety of manual run throughs and automated timedemos but regardless of which test method is used we monitor all tests to ensure performance is consistent. Where there are spurious results or dips in performance we will note this. We also do multiple run throughs then take the average of these and report that figure to you. The test setup is as follows:

* Intel Core 2 Quad QX9770

* Asus P5E3

* ATI: Catalyst 8.4

* nVidia GTX200 Series: Forceware 177.34

* Other nVidia cards: Forceware 175.16

Cards Tested

* ATI HD 4870

* ATI HD 3870

Very interesting results, especially Crysis. Given the feature set is identical between the 4850 and 4870 you'd expect the only differences be due to slightly increased clock speed and significantly increased memory bandwidth. That being the case the OC'd 4850, especially if the memory is OC'd, should bring performance closer to the 4870 - as in fact the other games show.

So what's going on in Crysis - driver optimisations for the 4870? Heat throttling for the 4850?

I got this card (the 4850) built-in the Dell Studio XPS (currently in production, hasn't shipped yet). I am not a gamer at all and personally only care about the connections that the card allows me to do: I noticed two DVI outputs and one s-video output. Does this mean that I can connect simultaneously (a) two computer monitors (one for each DVI) plus a TV through the s-video or (b) one computer monitor to one DVI output and a TV to the other DVI output? I would really love to be right in my guess. And this is pure guess, as I am not very familiar with the terminology of graphics cards (my old PC packs a whopping 64MB graphics card and I don't even know the brand). I would really appreciate it if someone would clear this little doubt of mine. Thanks.
