Are they even going to be made? Looking on newegg, it seems like there aren't any 3870x2 cards that have 1GB of useable memory. Chances the 4870x2 also follows this pattern? That would definitely induce me to keep my GTX280 if I couldn't get a 1GB ati card?
 
They're coming... saw an Aussie etailer say July 8th ETA but likely by mid July we should see the first ones appear.
 
Unfortunately I think the australian retailer is misinformed or something.
 
I'd be surprised if they appeared that early - and also annoyed since it would force me to sell a couple 4870's.
 
Wonder why you think it will take so long? I'm delaying my build to get a 1gb 4870, but maybe I'll just get impatient and waste some money on the 280. $300 isn't that much money if I have to wait a month.
 
By the way, what is the 4870x2? Is that like the 9900GX2 where it's running in Crossfire on a single card?

Maybe, Maybe not, gotta wait until release, but from the INFO being leaked, there is no crossfire on 1 single card....thats just a rumor though but its some new bridge chip..
 

did any company even announce a 1gb 4870 model? I am on a 30inch @ 2560x1600 still using a geforce 8600 :/ would like to update to a 4870 But people have told me i should get a 1GB card such as the GTX 280
 
link?
btw yesterday someone posted a nehalem + 4850 test rig and there was some mention of 4870x2 2gb in all the translation gibberish. :rolleyes:
 
Kind of surprised there aren't any 1GB 4850's floating around. The 4870 I can understand with the shortage of GDDR5.

Only if you want to waste an extra $250 for minimal performance gains over the HD4870.

Honestly, the HD4870X2 should be good, but I'm still waiting for reviews.

Guess i will just wait also for the x2 results, i wonder is it supposed to be better than X firing to 4870's? any ideas?

Its going to depend of several factors including which Motherboard chipset you have. For instance if you have a P965 chipset like I have you can Xfire but one of the slots is 16x and the other is 4x. That will really mess things up for Xfire. You ideally want two 16x slots.

For folks like me the x2 is really the only option unless I want a new MB, which I really don't need right now.

http://www.newegg.com/Product/Product.aspx?Item=N82E16813136044 This is my mobo purchased it about 2 months ago. Will xfire be best way to go with it or X2?

If xfire will be a better setup i will purchase the cards asap before they run out @ new egg.
Thanks for the help

That board supports crossfire.

The *_rumor_* goes that the 4870x2 will be superior to two 4870's, because of an improved bridge architecture and shared memory. Best to wait and see, though...

Personally, I'm going for a 4850 in the meantime, and plan on upgrading to something better when the next set of refreshes (4870x2, GTX 290/280x2?) hit.

i can not talk about 16x/4x crossfire setups, but the 8x/8x vs 16x/16x setups has NO performance gains at 19x12 games, same thing for 8x/8x SLI vs 16x/16x SLI. It is kind like the PCIe 1.0 vs PCIe 2.0 issue at 8800gt lauch: people do NOT need to buy new motherboards to enjoy the 8800gt performance, It takes a small memory(256/128MB) videocard at HUGE resolutions to saturate the PCIe bus with data: cards with 512MB or greater resolutions do not need to use the PCIe bus that much, even when crossfiring/SLIing.

But i agree with you 512MB is NOT enough for 2560x1600 if you go above 2xAA: you can not run 3dMark06 at 8xAA with an 8800GT 512MB, The Witcher crashes at 4xAA and many more memory related issues. The 4870 has been tested at 2560x1600 in many games swith good results, but no test at or above 4xAA, so it MAY be better to wait for 1GB 4870 or a 4870x2, but i would not recommend an 280GTX at the current price tag: 2 4870s in crossfire, even at 16x/4x would cost less and as long as you keep AA at 2x tops you are good to go.

I got the information from this article at tweaktown comparing 16x 16x vs 8x 8x 2.0

http://www.tweaktown.com/articles/1472/1/intel_p45_vs_x48_crossfire_performance/index.html

They definitely noticed a difference so thats why I would expect that 16x 4x 1.1 would be even worse wouldn't you think? I would like to see some tests with a 16x 4x 1.1 mb but I doubt we will see any.

For me? I won't be going any higher then 1900x1080 so I wonder what the difference would be. I would certainly like to go over 2xAA when I can. Thats why I was thinking the x2 card would be better then 2 cards for my particular setup. What do you think?

geoking,

could you point me to some 8/8x crossfirex setup benchies? I heard that crossfirex really needs 2 16x pci-e lanes. I'm currently on a 975x board and would like to know if i'd need to jump to a crossfirex compatible board to take full advantage of the new cards in xfire.

That was most likely my information source at the time:

"Overall, the change in platforms results in a speedup of only a few percent. Games that ran smoothly before run a little faster, while slower games such as Crysis or Flight Simulator X don't yet benefit from Crossfire optimizations in the WHQL drivers. Currently, going from x8 to x16 for Crossfire really only offers a tangible payoff in higher resolutions. At the highest resolution of 1920x1200 pixels, only a single test enjoyed a really meaningful speedup as a result of the faster interface, going from 53 to 63 fps. The remaining resolutions were already running smoothly at more than 70 or 100 fps, so any improvements here only help the overall performance rating, not real-world playability. "

I think that there are many more reasons to buy a new motherboard than a 53x63fps gap (game experience tops at 60fps anyway). Many of these reasons explain the X48vsP45 gaps.

I am also a 975x owner: a 2 years old P5WDH DELUXE, running an [email protected]. My personal decision is based on a future nehalem build, not a true crossfire graving, but living in Brazil i must dump over US$350 to get a 4850, for that money people in Taiwan and USA can get 2x4850 and a couple of 120mm fans to help airflow:cool:

If money and performance is the subject just grab a single 4850, overclock the hell out of it and see if they can give you good gameplay (they CAN at 1920x1200 BTW), and go for a second 4850 (it will be cheaper in the 2 weeks of tweaking) if you are not happy already.

Just for flaming: will Nehalem support SLI on the first MOBOs? So far only CF is a sure bet!
