5870 crossfire? yes or no!

Why do people always say 2 5870's is as waste at 1920, when games benches on websites show it does in fact make a difference to min and max framerate. Plus it gives you the opportunity to max out AA and other eye candy which you may not be possible with a single gpu even at 1920.
 
Yes definately worth it - I had this and think it's worth it at 1680x1050, but I since upgraded to 1920x1200, and I still reckon I could do with more graphics horsepower - especially for crysis games, and for when crysis 2 comes out... Dirt 2 is good performance will have to wait to see what the new Dx11 AvP is like but upping to that res and running dirt 2 in dx 11 mode is still only something like 70fps - so although it's faster than the eye can see, it's not going to be long before that gets pushed even harder in future games! (ie when more tessalation comes on the scene, just look at the heaven benchmark with these settings) - so as you can probably guess I'm already waiting on crossfire 6870's :P

Ignore these people who claim that it's always overkill at your resolution - u will always notice the difference, like I said I don't think it was overkill on 1680x1050 - I think mostly they're jealous that they can't afford it.

+1.
 
I agree with everyone else that said get one.

I have 2 and they are brilliant cards - eat 'AA'for breakfast.

Couple them with a Nvidia card for PhysX as I have and they are even more awesome - Batman AA is stunningly fast (is stunningly a word?!?)

Yes.
 
5870 is a good GFX card by itself never mind xfire, but all we get from the 5770xfire boys is we only payed £240 and we out gun( E-PEEN) yous :), IMAO yip it might cost £300 more but look at the performance when we go xfire.

But you can build another PC for £600 with 5770xf, we hear them cry!!!!

We out gun the 5970 lol who has the bigger guns :D and the 5970 boys have to spend £530 to out gun us thats £1060, phew lol and then they have the biggest guns :cool:.

LOL - :eek: but you can build two PC'S with 5770xf, we'll hear them cry!!!!

No offence to the 5970 boys more power to you, just slipped this in before some 5770xf boys come in...;)

EDIT--- IMAO --- > Flanno < anyone else notice he has 5870trif, made my day heehee, l wunder what the 5770XF boys have to say about that, go Flanno nice one.

I'm also about to order the saphire 5870 tommorow when I get paid to go with my Gigabyte 5870, I ordered a Antec TruePower New Blue Modular 750W and have installed into my pc. I am a little concerned as read a comment there stating that you'd need a 900W PSU, that seems a little excessive to me. Do you think my 750W PSU should be able to handle xfire ?

Running Q6600 @ 3.3Ghz + 8 Gig 1000mhz Ram + Antec 902 + 1 DVD RW

750W would be fine for a single card, for 2 x 5870 you proberbly would need a larger PSU.

What else are you running - HDD's, fans , USB acc's it all needs to be taken into consideration.
 
Radeon HD 5870 CrossfireX (2-way)
A second card requires you to add another 188 Watts. You need a 700+ Watt power supply unit if you use it in a high-end system. That power supply needs to have (in total accumulated) at least 55~60 Amps available on the +12 volt rails.

Hope this helps, l got a Corsair HX850( see sig ) to be on the safe side, and l do believe some one on the forum is using one with no probs at all.
 
5870 xfire uses 561w at load if that helps thats with a i7 @ 3.3 so add fans, hdd etc 750W with 80 plus certified power supply should be enough for 2x 5870. People get so hung up on ZOMG i need a 1000w psu know very little it seems
 
well the 2nd card will be powerd by PC power & cooling 1000W turbo cool PSU. 88A 12v rail

System will be 2 X 5870's crossfire, 4 hard drives, asus D2 7.1 pci sound card, 2 optical drives. 6 gig corsair GT, plus i7 4GHZ water cooled CPU and chipset. all fans power by zalman fan controllers with there own PSU. should be ok on the power front for X fire with the above PSU.

all in a UFO black cube!
 
I now have crossfire 5870's installed and everything works as it should with cats 10.1 no issues so far. fast and stable so no complaints. pleased i went with crossfire!
