6870 vs 5870 which is better.

post #1 of 34
Thread Starter 
Now i know most of you will immediatly say the 6870 but i want to know in what ways each card is better over the other.
Which is better value, which works better with crossfire, tripple crossfire, which has better overclocking ability, which has a better selection of after market coolers air and water. Which one would work better with the asus crosshair iv mobo's hybrid video card technology. (which if i recalll correctly alows you to use ati and nvidia cards for the features if both)

Anyone who can help me with any of these, thank you smile.gif

If you want trifire the 68xx can not do it. The scaling is better on 6xxx cards and use less power.

For the multi brand set up, you need the Crosshair iv extreme. It has what's known as lucid hydra. It works well but old school crossfire wins.
CIV extreme is also around $100 more than the formula. Save the money from switching extreme to formula and put it into graphics. That extra 100 could be a 6950 vs a 6870. Extra memory as well as performance and the chance to unlock to a full 6970

Also, for aftermarket cooling the 5870 will win as it was out forever and a day. Overclocking a 5870 will beat the 6870 card to card but 6870 crossfire will win as scaling enables you to use more of the power from te second card. If you have to have crossfire, buy the 6870s. Plus they run nice and cool

6870 without doubt,only exception would be if you want tri-fire as guy above said.

unfourtunatly im sure it will also be signifigantly too expensive for its worth.
but thanks for the suggestion smile.gif

and also thank you all for the other comments.

Would a trifire 5870 exceed a crossfire 6870 signifigantly? or would it be more worth it to crossfire the 6870 and add an nvidia card for physx purpouse

Out of curiosity, are you somehow planning on adding this to the machine in your sig? Anything more powerful than that 5770 and your CPU is going to bottleneck it...

That PSU would be an isue as well.


PhysX isn't particularly useful IMO, since not a lot of games use it. A 3rd 5870 would give a much higher performance boost, though you'd need a really beefy CPU to utilize a monster like that.

Trifire 5870 would not pass the crossfire 6870 by much, your looking for roughly the same power, +/- a few percent. The cost is way out of hand at that point. Also your heat, sound and power usage would be insane.

If you think you need that kind of power try the 6870 crossfire. If that fails, you could always upgrade to the 1gb 6950. A pair of 6950s (2gb) run around 550 after rebates. Pair of 5870 around 440 AR.

Step that up to trifire and now we are talking around 660. At that point you could be running the 6950 crossfire or even bump to full 6970 crossfire.

Your save money on your power bill, your sound would be less and performance greatly enhanced by using a 6xxx card if you need more than a single card. Also you would need to upgrade your psu for trifired 5870s.

The lucid hydra chip is used for mixing nvidia and ati cards. You can mix brands on any crossfire capable motherboard.
