ATI HD 3800 Review Thread

[EvilBellyLint]

Anything to suggest that it would or would not be possible to run
(2) current HD 3750's and (2) Dual-chip HD 3750's (when available)
together in a Quad-Fire configuration?

in theory hell yeh... but no idea tbh.

AMD/ATI are striving to get this sort of thing to work well so i guess so. After all they are all the same cores.

Yes X2s only have one crossfire connector I guess 2 x HD3870 + 1 HD3870X2 should be possible though.

Does using a P35 board compared to a x38 cost alot of performance on two 3870 in crossfire?

yes.

It depends on the application. For instance there isn't much of a difference in something like 3DMark05 but if you look at 3DMark03 you'll see a significant difference.

Can anybody give me a link to some 3870+3850 CF results? I must be retarded or something, I cannot find them...

Here are the results with X38, all we need is results from a P35 (which I haven't found yet).

This link will explain PCI express lanes using the P35, X38 and Blitz

Hey guys I have a question I just jumped into the post that seemed close to what im looking at. I have a p5e (x38 chipset), e6600, Plus I just purchased and recieved 2 3870's for crossfire. I have 3 monitors. what is the best way to configure my setup. i want to use the crossfire of course i also want to use my third monitor can anyone help?

[mascaras]

Hi guys

what you think


2x HD3850 512MB PCS edition (720/1800) with samsung 1.0ns and cooler (Today )

>> http://www.powercolor.com/pt/product...ProductID=1660



or wait 5 more days for 2x HD3870 ??



i think the HD3850 512mb PCS edition +- same thing ............ (less 2-4 FPS in games than HD3870 )

You tell us. YOU have the cards, so also 2 versions of manuals with them, a paper and a software version, plus the CCC...

@ mascaras: i'd say control yourself! Just wait for the 3870's of course. Or do as i: wait for the X2's to be released (Jan/Feb) and reviewed, then choose best price/performance setup from the complete ATI offering.

[mascaras]

done


tomorow 2x HD3850 256mb just for 5 days then :

2x Powercolor HD3870 PCS Edition >> http://www.powercolor.com/eng/produc...ProductID=1647

jan/Feb change for HD3870X2

[Unbornchild]

Are you mad? and/or filthy rich? and/or joking?

Well, you test them then while i watch and wait! (and save!)

im serious , tomorow new computer with 2x HD3850 256mb

and 5 more days i switch for 2x powercolor HD3850 512mb PCS


i will review Both , in the review section

[HousERaT]

I look forward to seeing how the Powercolor cards run with the 3rd party cooler. I'm not finding the 3870s to be hindered by the stock cooler. Maybe on the memory side but not on the core.

zotac 8800GT 660mhz core + X2 3800@2800mhz












HD3870 DEFAULT + X2 3800@2750mhz

So I'm using 2 3870's on a p975 chipset. So far my 3dmark06 scores almost hit 16k with an e6600 running at 3.6. I see also higher framerates in every game at 1920x1200 than a 2900xt. How much more performance increase am I suppose to see with a x38 chipset?

i can tell you next week , when i switch to 2x Powercolor HD3870 512mb PCS ( i also bought a X38 mobo)


tomorow only tests of 2x HD3850 256mb + X38 (Asus P5E)

[pphx459]

Yes, that would be very nice, I just wanted to see if anyone was using the same configuration but swap out the board to an x38. I love the cards, they are blazing fast!

The dilemma I have is that I have a few Q6600's ready to go but I read that the 975's can't handle the quads very well. Wondering if I should just sell them, make a few dollars or 2 and wait for the penryn's or upgrade the board now. If the 3870's are much fast on the x38 then that makes my decision a lot easier.

[Mike EFix]

Ditto.
I get them in two weeks as well

[pphx459]

nice, just curious what's the availability on these cards nowadays?

[Mike EFix]

I think the wife ordered the 3870's through Frys @ 224.00/ea w/ 20.00 rebate. Availability is 2 weeks- or so I'm told

[STaRGaZeR]

Any problems running CF guys? All the games you can try actually take benefits of CF?

Waiting your results mascaras. Also, when you have the cards, some 3870+3850 would be nice

[pphx459]

I can tell you that running these cards in CF is a big improvement over a single 1gig 2900xt in all games I play, cod4, crysis, the witcher, etc...

[STaRGaZeR]

Have you tried OpenGL games?
