You're kidding about the first point, right?Quote:

Ignoring power consumption, it is theoretically possible to do, but it's a really really stupid idea.
I don't think that 4870 has such a huge power consumption as claimed. First of all, look at the results of the 9800gtx vs. 9800gx2. Do you see the tiny difference in power consumption? Does that make sense? (Hint: no it doesn't!) Do you seriously believe that the 9800gx2 consumes only <20W more than the 9800gtx? This contradicts all other reviews!
@Miwo: Take a look at the heatsink, there you will see that the contact area is protruded a little to make sure there will be proper contact with the core and headsink;
http://en.expreview.com/2008/06/24/f...and-hd-4850/4/
The result with Lost Planet are really weird. The 4870 does 23,9 FPS @1920x1200 NoAA NoAF and it does 23,5 FPS @1920x1200 4XAA 16XAF. That's only a 0,4 FPS decrease from enabling AA and AF and that pretty much out of this world to only have such a small drop....or is this driver related?
About power consumption though, I'll reserve judgment until there are more reviews. Although I don't really care about maximum power draw as long as it's quiet, idle power draw is a bigger concern for me as my PC is idle most of the day. BTW, it has been a known fact for a long time that NVIDIA's TDP rating is very conservative, while ATI's rating is more along the lines of what it truly will draw.
Earthwatts are made by Seasonic aren't they? Good 12v rails on those, so I see no reason why it can't run one. I'd get something a bit beefier for Crossfire thoughQuote:

that's not the best game to showcase 4870, after all, it can't even use AA in BioshockQuote:

Could someone explain what the cause for that is? What in Bioshock makes it not possible for an ATI card to enable AA?
Why wouldn't it be able to do a single 4870? A 2900XT draws more power than a 4870....Quote:

you can force it through driversQuote:

so why don't the reviewers test with AA then? are they just dumb?Quote:

And yes, most reviewers are a bit dumb sometimes. Others are always dumb.

yah, except r700 should be about 15% faster than a GTX 280...Quote:

It would have to come in a 1GB flavour however, and hopefully the fan isn't as loud as it looks. I really miss my Silencer from my X800 card, man that thing was quiet while still expelling air out of the rear of the case.
I'm not believing all these 220 Euro HD 3870 rumours with a link.
<-- Really wants to know if its true :eek:
