And it sure as hell is not clocked at 1ghz +

shouldn't that 3870 x2 be 4 ?

4 what, Flops? there showing a total of 640 sp's at 2 each.

4 what?

Its still only 2 flops per unit, it all checks out

1.056 Teraflops = 2 GPUs X 320 Shaders X 2 flops per unit X 825mhz

Yes benchmarks finally!

4xAA hit in COJ 1920 x 1200 is VERY small...3 frames

AA is fixed alright ;)

Buyer's remorse goes hand in hand with being a PC enthusiast :)

The 3870X2 is still a b1tchin card though! It will beat the 4850 and probably the 4870 in games that are optimized for CF

nice, looks 40% slower than a GTX 280 (on vantage)!?
(comparing to the other quad xtreme @ 4ghz GTX 280 results)

I have sitting here 2 3870X2's and a 3650 256MB as well as the 4850, I don't regret any, they will all sell to friends local or on the forums, :up: making the cost of upgrading go down. the 3870X2's are monsters, they will be "current cards" for some time to come.

Yeah the 3870X2 somehow got a bad rep (probably lackluster scores in initial previews due to poor drivers) But they perform great now and are priced very well, especially used! I saw one go for 180 euro recently when they were still 320 euro + at retail, I was tempted but I have to hold off until I see the GTX260 results and the 4850/4870 results

somethings not right with those they look to be the same card to me in both pics.

The 3dmark benchmarks are nice, this is really a very good result for such a cheap grafikcard.

But Crysis Benchmark with AA would be far more interessting.
Hope you can make it run soon.

1280x1024 and 1920x1200 with AA and very high settings.
I'm excited if the 512MB VRAM will slow the card down on very high settings in crysis.

If the 4870 is really 30% faster than this one, it comes pretty close to the GTX280, and this would be a disaster for Nvidia. (If the 4870 will cost around 350$)

And if ATI has a X2 version in their pipeline, waiting to be introduced in the next months, they have won the game, at least for this year.:up:

Wow look at the minimal perfomance hit no AA vs 4xAA in COJ. 3800 had the same behaviour? I've never played COJ :p:
