Enjoy it while it lasts ATI.

Unless nV screws G300 up (rebranding G200) then it may be a nice time but wont last forever.

If only they could get a damn seperate shader clock. With 1600 SPs running at 1.7GHz they could blow nV out of the water....

It's dissapointing to hear the memory had to be put so low...
Though I'd love to liquid cool my i7, then add a 5870 and liquid cool that also. I got a radiator at work that can likely handle a 10 kilowatt system, add to that it's constantly cooled by sub zero temperatures (during winter atleast), with a 5 barrel resevoir, and dual 24" fans (used to cool 3000psi hydraulics).

Even more dissapointing to see it can't keep up with it's dual 4xxx series cousin.
Also, GPU waterblocks just look so inneficient...

WOOOOOOOW extremely low temperatures... but not worth the 500W draw.
I think now am interested in water cooled video cards.

but honestly, i thought the gain will be 20% at least... disappointing.

You made a mistake on the test and benchmark page on the Crysis Bench config. It states you tested it at low quality. This would mean at least 100-150FPS....

Nice work but I also wish you guys tested Crysis at Very High settings.... its always great to see Crysis tested at its maximum threshhold.

Being a single card 5870 performs very impressively...
And the power usage is impressive too(Only on stock).

This is the best card for now and with a lil price dip it'll be fav. of all high end gamers.

I love the draw on their oc 1 gpu is greater then 2 older gen gpus draw that's just hilariously bad results. Still with the waterblock set up maybe you can afford the 1000 dollar electric bill with you're fastest possible machine. Sorry but as far as ATI venders powercolor is low on the list of ones i trust. Poor 5870 gpu wasted on excess and ya can't waste those things, hard to come by with tsmc doing jack in the yields department.

I have convinced myself watercooling is a must for GPUs.

I am running a watercooling setup on my CPU alone at the moment. Despite majority of heat gone from internal case, my HD4850 card would barely escape overheat in room temperature of 23deg C in UK winter. I once tried moving my soundcard closer leaving 2 inch clearance from HD4850 and it crashes every single time when I run Mass Effect. Now it crashes once in a while and I am 100% sure it's due to overheating of the GPU. Load temperature reaches 106 deg C. The card crashes at 110 deg C.

so i`m 1 of the few people who was not surprised by the outcome!? 2 4890`s packs a decent punch, the fact 1 5780 can keep up with that is not bad, I did not expect anything different...

Keen to find out if DX 11 will make a difference once its mature...

I don't understand how the 5870 can be slower than a 4870x2/2x4890. Aren't the specs EXACTLY the same, except for the 5870's HIGHER clocks and that the 5870 has all those specs in ONE gpu die rather than two?

i've seen in many sites that 4890 in crossfirex scale eceptionally well.
4890 crossfire even beats gtx 295 (gtx 275 sli)! but a single 4890 is
equal or less in performance of gtx 275. its as though the card was made
for crossfirex.

oh, another thing- haven't the 4890s been able to hit/exceed 1ghz for a long time now already.. on air?!?! What's special about this then?

A note on your setup issue: there isn't really any "input" or "output" nozzle. Your water will not change temperature very much before and after one single component (GPU/VRM/VRAM). Also, after it has made a few passes, the entire water system pretty much gets to one temperature and stays there (unless the load changes). The input and output is interchangeable between the two nozzles.

^ +1 to jonxor. With these blocks, it doesn't matter which is inlet or outlet...and once your temp reaches operating temps, they will only go up depending on load and your ability to dissipate heat via the rads and ambient temps.
