lol no brainier 5870 for sure... 6870 is slower than a 5870. however crossfire 6870 may scale better than two 5870's.

I actually started to have that issue with my 5850s. Turned out I had actually caused a piece on the back of the card to explode from the sheer amount of heat it was dealing with. Had to RMA and they replaced the entire card with a new one.

I cant RMA i,t the card is way past its warranty i think, ive set the fans just about right to keep the card at 85c playing bf3 for 4 hours, are the temps anything to worry about?



will re applying the thermal paste help(cards are about 2-3 years old)? I cant really get a aftermarket cooler from them because there is not enough space

5870's are actually considerably faster then there newer counterparts.
then main advantage if the 68xx is that they have higher price performance and Higher Watt to performance then the 58xx.

there are a lot of pros and cons, so i am having a hard time picking my setup


crossfire 5870s
cons:runs hot, video cards are 2 years old,fans are loud
pros:much faster then a single 6870,looks nice,can max out almost any game.

msi twin frozer 6870
cons:a bit slow,only 1gb ram.
pros:6 month old, very quite, never goes above 78c,has warranty.

I would probably be best to keep them under 80c. My card blew out at 82c and it did not look pretty... If the cards are reference design then a good idea would be to look into a watercooled loop for just the GPUs or a full setup. If I had reference cards I would have switched to WC a long time ago. The thermal paste may help but you have to be careful what paste you use, GPU require non-conductive paste if I recall correctly.

5870's aren't that bad with heat... you just need a bigger case.
