I am considering to drop in another Asus 5770 on my 2 weeks old new rig (i7 920, P6T SE mobo, Asus 5770).
From the look of the motherboard P6T SE with single 5770, it seems like there's hardly enough space for a 2nd 5770 to be put in the 2nd PCI-E 16x slot, anyone try doing crossfire with Asus 5770 on a P6T SE before?
I'd want to make sure before I order another one and only find out that it's not working.
You're worst enemy will be heat. I tried to Crossfire (2) 4870's on a P6T and had HORRIBLE heat issues with the top card. Granted this was a 4870 which runs hotter than a 5770. However, I am just telling you my experience with a dual card setup. If there is an extra space between the cards you tend to have less heat issues because the air can circulate. However, when they are tight against one another you have to make sure the top card has fresh air to suck in, not the hot air from the card below.
my 5770's on my board don't even get warm 790xt-ud4p also antec 300 case with 4 120mm antec fans and 1 140mm in the top... at 960/1300 and AUTO fan speed my top card only hits like 82 or 83 degrees celcius after half hour of furmark... gaming has never broken 70 degrees... V2 sapphires... nice cards
