Why would a consumer need those? Buy ATI : DOriginally Posted by RaZz!
the 4850 is a hell of a sexy card!
and it's as low as around 140 € here in germany. i'm definately on the verge of buying one - but on the other hand i can't estimate in which direction nvidia is heading with it's physx and cuda.
E7200 @ 3.4 ; 7870 GHz 2 GB
Intel's atom is a terrible chip.
I don't think you will have to worry about that for at least another year and who knows how things will be by then.the 4850 is a hell of a sexy card!

Does anyone know if the 4 mount holes at the side of the 4870 GPU are the same dimensions as the 1900XT
This is the block i am using on my 1900XT

Same as 3870, i'm not sure about 1900XT, i never had one.
cf on p35? don't do it man. i'd recommend a 4870 and clock it like crazy.
Ryzen 9 3900X w/ NH-U14s on MSI X570 Unify
32 GB Patriot Viper Steel 3733 CL14 (1.51v)
RX 5700 XT w/ 2x 120mm fan mod (2 GHz)
Tons of NVMe & SATA SSDs
LG 27GL850 + Asus MG279Q
Meshify C white
I'd do the same, CF on a P35 is severely limited by the fact that is has to use the 2nd card on a 4x PCIe gen 1 bus and this second bus is coupled to the southbridge which hampers latency and bandwidth even more. So get a 4870 and clock it like crazy or upgrade to a P45 or a X48/X38 board. I'd go for the former option, Nehalem is not too far from now....

Don't..
Hey bro, i will be glad to help, i will have a full review up once my new ram arrives in about 3 hours from now, review will be up later tonight, i have all the games up and ready to be benched, i just need to get my memory stable.P45 looks good for now as far as crossfire goes.
I can tell you this, i got a little over 19k 3dmark 06 @ 1920x1200 with my cpu at 3.8ghz and my memory running at a horrible single channel, 1 dimm 2gb at 570mhz cas 7, they have a better cpu at 4ghz, and memory configuration, and scored 1,000 points less.......my results are with vista 64 also.
4870 + some basic watercooling + hard vmod + OC LIKE A PSYCHO = win
Hmm I hoped I waited for the P45
Now I will get the 4870 and WC it with a EK.
But cant wait to see 4870x2 results.

Thanks man!! Will search for your results when I wake up in the morning. If you gonna post them in a new thread please send me a PM with a link to it.
As you have already mentioned Asus P45 seems to give the expected performance. Maybe is only a Gigabyte thing with those weird results but then again the difference really becomes obvious in game tests. Vantage shows a bit of difference and then you can clearly see the difference in game tests. 3DMark06 shows little difference even in their tests.
Looking at the review again the difference is clealry visible when 4xAA/16xAF is used. So please make sure you test bench with those settings too.

Ok i have no idea what to buy a HD4850 CF setup or the HD4870. It will be used for gaming at 1680x1050, and it only has to last for 1 year max
Every new AMD/ATi generation 1 buy new cards. So any tips?
And yes i have seen all the reviews but just can't make up my mind about what is the right thing to pick.
Intel Q6600 G0 @ 3600MHz
Thermalright Ultra-120 eXtreme / Papst 4412F/2GL
Asus X38 Maximus Formula SE @ 1102

Dual Jetway ATi HD 4850 512MB @ 750 / 1100MHz
Triple WD 320GB S-ATA II 16MB
Dual Dell UltraSharp 2007WFP
Antec TruePower Quattro 1kW
well, if your on a tight budget and im assuming you are or you would consider 4870xfire, why dont you buy 1 4850 and see if that suits you and if it dont then you could always add another or a 4870.
Particle's First Rule of Online Technical Discussion:
As a thread about any computer related subject has its length approach infinity, the likelihood and inevitability of a poorly constructed AMD vs. Intel fight also exponentially increases.
Likewise, the frequency of a car pseudoanalogy to explain a technical concept increases with thread length. This will make many people chuckle, as computer people are rarely knowledgeable about vehicular mechanics.
Rule 2:
When confronted with a post that is contrary to what a poster likes, believes, or most often wants to be correct, the poster will pick out only minor details that are largely irrelevant in an attempt to shut out the conflicting idea. The core of the post will be left alone since it isn't easy to contradict what the person is actually saying.
Rule 2A:
When a poster cannot properly refute a post they do not like (as described above), the poster will most likely invent fictitious counter-points and/or begin to attack the other's credibility in feeble ways that are dramatic but irrelevant. Do not underestimate this tactic, as in the online world this will sway many observers. Do not forget: Correctness is decided only by what is said last, the most loudly, or with greatest repetition.
Remember: When debating online, everyone else is ALWAYS wrong if they do not agree with you!
Yes, no problem, it will fit. Since the x1xxx ATI has used the same mounting holesDoes anyone know if the 4 mount holes at the side of the 4870 GPU are the same dimensions as the 1900XT
This is the block i am using on my 1900XT

I'd go with the 4870... 2 reasonsOk i have no idea what to buy a HD4850 CF setup or the HD4870. It will be used for gaming at 1680x1050, and it only has to last for 1 year max

1.) In cf, adding a 4850 would slow your 4870 down to act almost like a 4850.. load balancing.
2.) In time, if the 4870 gets a bit slow for your requirements, a second will be cheaper then what you bought the first one for. Additionally, adding a 4870x2 may be a very viable option for a tri crossfirex setup. In a years time, they could also be quite cheap.
would this work well together?

with 2 x 4870 1gb cf
also is a e8400 @ 4ghz enough for no bottlenecking
No, I think he had a date tonight...
He and his EK Supreme are out for a night on the town!
Should work great together. 4ghz should be adequate, I'd doubt there would be any noticeable bottleneck at that clock with these cards.

Looks like R700 is in my future:
Article by CNET
Wow, if true then R700 is going to be incredible.For ATI, the execution of this chip-ganging strategy is the key. And this is where ATI appears to have been successful. "The inter-processor communications. Getting that to work has been the trick. This is what ATI has done. They've come up with this stellar way of doing inter-processor communications so they can in fact get the scaling," according to Peddie.
...*snip*...
AMD-ATI's upcoming R700 (rumored to be called the 4870 X2) two-chip graphics board will be the ultimate test of this strategy.
"It's a new proprietary inter-processor communication technology. If they put these two chips on one board and it does scale properly, then they have pulled off a coup," he said.
"When you gang up graphics chips (using the traditional Scalable Link Interface or CrossFire technologies) they roll off pretty fast. ("Roll off" implies that performance doesn't scale up well.) "So when you put two boards in, you don't get twice the performance but you (only) get one and a half. You put four boards in and you (only) get about 1.7, 1.8. What ATI is saying is that with two chips using (their) proprietary inter-bus, they will get 1.8 (the performance) with two chips. If that's true, you can expect to see four of them giving you something around 2.5."
Getting 2.5 times the performance from four boards would be a masterstroke for ATI.
The previous ATI dual-chip solution was very different, Peddie said. "The HD 3870 X2 was not a proprietary bus but a CrossFire connection. The CrossFire connection and the SLI connection are at the very, very end of the pipeline. Not the most efficient place to do an inter-processor communication. That's one of the reasons ATI has abandoned it."
Of course. It was done before the card even launched. Would you expect any less?any guides yet?
http://www.xtremesystems.org/forums/...d.php?t=190990
It doesn't change the fact that scaling is hurt by the fact that 1 GPU stalls (adds frametime) while it waits for data from the other GPUs memory in the case where games are not coded with multi-gpu in mind.
This also has nothing to do with microstutter, but we'll see.
Seriously man, you should give up with the predictions because you have a bad history of being embarrassingly wrong.
You have presented us with an "I'm in the know" attitude and made plenty of predictions but let's take a short look at them:
http://www.xtremesystems.org/forums/...postcount=1524
http://www.xtremesystems.org/forums/...postcount=1543 Ohh, you know so huh?
http://www.xtremesystems.org/forums/...2&postcount=88 I'm not saying that it factually is or isn't. But we will see won't we?
http://www.xtremesystems.org/forums/...9&postcount=96
And here is a real gem: "That and maybe I've seen an R700"
Let me be the first to say it - yeah right.
It's pretty clear that you don't have any more clue about the truth of the wild rumors flying about then the rest of us. Just sit back and wait for the truth to come out instead of implying false authority on the subject. They are just companies and making them compete is good. You should be hoping that ATI makes a good card even if you don't plan on ever buying one.
