[Compare] HD3870 Crossfire vs 8800GT SLI

why do u guys still bother with xp its a dx10 card it should be tested on vista



1st cod 4 bench i found was on toms, but its 975 v680 so the ati cards are at a slight disadvantage and its on toms who gets nv money for their ads but ill keep looking, its within 1-2% so ati wins the price to performance and x38 they should win

i will be running at 1920x1200, so the gt is kicking ass..

i wonder just how much bus speed difference will affect the outcome on a x38

What source did you get your info from???

My source is my personal experience with having a GTX and 2 x 3870's. The GTX was able to play CoD4 at 1680x1050 16x/16x with no hesitation. The 3870's in Crossfire caused me to reduce my resolution to 1024/1280 before it was playable. I am hoping that this problem is taken care of in Catalyst 7.12. I just recently installed the Multi-GPU patch from M$ and haven't had time to play CoD4. If that fixes the problem, I'll let you know.

Are you using SP1 rc in vista 64?

Good post.

Crossfire works great in my BX2 rig under Vista x64. Also HD 3850s are down to 144usd @ BB in the US.

http://www.bestbuy.com/site/olspage....=1194053242019

They have HD 3870s for 193usd and they are always OOS. So are the 3850s now :p:

Personally, I really wish Intel had bought ATi instead of AMD.

very nice comparison, very well laid out :)

Very nice, thank you! Just what I was looking for and best of all, excellently laid out for our table searching eyes. :D

All good, especially Xfire scaling and nV AA/AF perf, but this ATi core with AA/AF really does take a monstrous hit. They need these issues resolved and its definitely something integral to the core itself if it hasn't been since R600. I mean -20FPS by 8800GT SLI and nearly -80FPS by 3870 CF!? That is seriously an area needing attention.

Would be nice if someone compare 3870 with cats 1.12 vs 8800GT lastest drivers.

nVidia has shot themselves in the foot by limiting SLi to their motherboards. Having said that, the firing squad show that in some cases SLi can scale close to 100% per card and that the only way to play crysis at 1600x1200 on very high at 30fps is three ultra's.

What I want to know is if xfire wil scale as well with 3 and 4 cards and if there will be x38/x48 boards with xfire(4) capability or if AMD are going to keep it to spider to try and shift phenoms.

interesting comparison and also good test

I can tell you it's not.
I'm the owner of crossfired 3870's, and I refuse to use Vista.

I've used XP 32 and now on x64 with these cards, and yes, crossfire does make a big difference. You just need to use drivers other than the ones on the CD.

Right now, the crysis hotfix drivers work very well. Even in games other than crysis.

This comparison rocks :D

Should definitely help anyone building a new rig anytime soon

Hmmm.... Kinda makes me consider dropping my 590SLI board and dual 88GT's for the new 790 board and dual 3870's.

THis thread makes me wonder something similar as well..

Newegg has a review of the ASUS L1N64 SLI WS where the reviewer states that he/she put in a crossfire setup and it worked. I didn't think Xfire would work, especially in an Nvidia chipset motherboard... So, is it correct to say that in certain motherboards you can run SLI or Crossfire? Has anyone done this successfully here at site - that anyone knows of?

I would suspect that if it can be done, Asus would be likely to be one of the board makers that support both - intentionally or unintentionally. Anyway, I've always like Nvidia products but I'm a big AMD fan.... Maybe it's time to look at the AMD Chipset boards.

this helps a lot.. i'm looking for my new card in this near future lol

ati on fire !!

nice tests
