Assassin's Creed
Even at 2560 x 1600 the high end configurations are bumping into a frame rate limiter, any of the very high end setups are capable of running Assassin's Creed very well.
Oblivion
The GeForce 9800 GTX+ does very well in Oblivion and a pair of them actually give the 4870 CF a run for its money, especially given that the GTX+ is a bit cheaper. While it's not the trend, it does illustrate that GPU performance can really vary from one application to the next. The Radeon HD 4870 is still faster, overall, just not in this case where it performs equally to a GTX+.
The Witcher
We've said it over and over again: while CrossFire doesn't scale as consistently as SLI, when it does, it has the potential to outscale SLI, and The Witcher is the perfect example of that. While the GeForce GTX 280 sees performance go up 55% from one to two cards, the Radeon HD 4870 sees a full 100% increase in performance.
It is worth noting that we are able to see these performance gains due to a late driver drop by AMD that enables CrossFire support in The Witcher. We do hope that AMD looks at enabling CrossFire in games other than those we test, but we do appreciate the quick turnaround in enabling support - at least once it was brought to their attention.
Bioshock
The Radeon HD 4000 series did very well in Bioshock in our single-GPU tests, but pair two of these things up and we're now setting performance records.

Somehow MSI seems to have done a better job with 4dB less.

I thought it was only Johan, and it was sort of understandable since he's not a native English speaker, but it seems most Anandtech writers don't know the difference between "its" and "it's"."It's" means "it is" or "it has" (just as "he's" or "she's"). When you're talking about something that belongs to something else, you use "its" (or "his" / "her").
In a sentence such as "RV770 in all it's [sic] glory.", you're clearly not saying "in all it is glory" or "in all it has glory"; you sare saying "in all the glory that belongs to it". So you should use "its", not "it's".
Even if you can't understand the difference (which seems pretty straightforward, but for some reason confuses some people), modern grammar checkers will pick this up 9 times out of 10.

I am not a native English speaker, but I am well aware of the difference. I am also sure that reviewers are also ... it's just that - with all this text, we can forgive them, can't we?I have a bachelor of computer science, studying for higher degree, but: I look at the technical side of the article, so I don't even notice the errors :D (although I can tell the difference I simply don't see it while reading)

Oh, I forgot: maybe I'm just being too enthusiastic ;)JarredWalton - Wednesday, June 25, 2008 - link
More likely is that with a 10000 word article and four lengthy GPU reviews in two weeks, errors slipped into the text. I know at one point I noticed Derek says "their" instead of "there" as well, and I can assure you that he knows the difference. I know I use Word's grammar checker, but I'm not sure Derek even uses Word sometimes. :)araczynski - Wednesday, June 25, 2008 - link
of the 4850's, slickdeals has posted a sale, between rebate and coupon off...$150 each. can't beat that bang/$ by anything from nvidia.first ati cards that will ever be in my computers since i've started with the voodoo/riva tnt :)

Page 15: first reference to "GTX 280" should be "GTX 260" instead.Page 19: I think you meant "type" not "time" in this paragraph.

This review is flawed. It shows greater than 100% scaling for Crossfire 4870 in Call of Duty 4. Why don't they just give us the raw numbers for both single and dual cards in the same scenario? Why use a method that will artificially inflate the Crossfire results?Denithor - Wednesday, June 25, 2008 - link
If you read the comments before yours, you'd see the answer.Experimental error and/or improved scaling for each card versus a single card. Read the earlier comment for more details.
