Hello,
Had to RMA my Sapphire 4870x2 due to it overheating. I did a full format and Win7 reinstall and used the latest drivers for everything. However, with the new card I'm getting constant freezes which forces me to reboot. Sometimes I get a black screen and the fan on the vid card goes to max or sometimes the screen just freezes (though I can still hear sound). It doesn't appear to be overheating (I monitor Catalyst Control Center and it's staying below 60 C will playing Civ 5). I bought a cheap Diamond 4350 vid card to use while I was waiting for the RMA and have had no freezing issues after swapping out the new card for this one even while playing Civ 5.
Could this be a PSU issue? Insufficient power? Thanks! Below are my system specs...

1 x GIGABYTE GA-EX58-UD5 LGA 1366 Intel X58 ATX Intel Motherboard

If the PSU handled the old card I don't see why it wouldn't handle the new one. Its specs certainly are sufficient. It sounds like you just get shipped a bad replacement card.

an 850W PSU should be more than enough for that computer.

Could be. It happens sometimes.

I had an issue very similar to yours, and it turned out to be my motherboard. It used to work, and then started acting up. I swapped in an older card and it was find, and the card I thought was the issue ended up being fine as well (ran fine in another machine).

Now the previously suspected video card is in another setup and is running like a champ.

I've read about a few others having the issue when the power to the motherboard and/or video card wasn't seated properly, or the 20-pin adapter they were using was at fault.

Thanks for all the responses! Sapphire claims that the diagnostic test on the card that they did before sending it to me showed nothing wrong but I'm dubious. Judging by the wear marks on the card it's obviously a refurbished card but to be sure I guess I need to find another computer to test it in.
