Right here goes. I have a coolermaster haf 932 case with a ud5 motherboard. Any one familiar with this set up? My graphics card is 4870 x2 fitted with a xtreme cooler. Now this thing takes up three pci slots, there fore covering my other pci ex x16 slot. Now i though about adding another card for cross fire and running three monitors. Curently running two still not enough desktop when editing photos. Right so i was wondering if i could put my 4870 x2 in the second pci ex x16 slot and then there would be room to fit a single 4870 with 1gb of ram in pci ex x16 slot one. Would there be anyloss in performance running xfire this way. It would mean me loosing my xfi platinum pci sound card but i could allways get a pci express one to replace it. If any one could help that would be great

The above board was supplied when i bought a tweeked Ultima Vanquish from over clockers last august.
Tweeks were haf 932 case.
ATI 4870 x2 Graphics card
Corsair tx850 power supply which i paid for but never got. They left the Tx650 in. So had to get a refund as the wouldn't let me just send the power supply back for exchange they wanted the hole pc to go back.
So i now running dual power supplies with relay. I Had a Antec true 380 lying round. So now using that to run my 8 hardrives and 3 dvd writers and front input bay for xfi platinum

You can run two graphics cards both at full speed (16 lanes each) in that motherboard so yeah it should be fine as long as everything physically fits, you shouldn't get any loss in performance.

Thanks for clearing that up for me, if only i could find an asus 4870 x2 that came with the advanced cooling the one one with 3 fans that only took up 2 pci slots that would be great. but untill then i will have to settle for a single 4870 1 gig.
Got to find a sound card now thats a good qality pci expess to fit in the pci ex slot above the first pci ex 16x I'm gonna miss my front inpt bay on the xfi
 
I dont think its the worst after all the spacing hasn't changed for years.
Expansion slots have been the same for years. it's the fact they now put the first pci ex x 16 slot third one down. 99 % of motherboards do this now. Agp was allways first slot this is where i see the problem to be not the fact they only 2 slots apart for your x16 slots motherboards should be bigger now with all these sli and xfire multi graphics cards.
 
Also there is enough room in the haf 932 case at the top to position the motherboard higher up in the case. There for allowing another expansion slot in the case and moving the motherboard away from the power supply when mounted in the bottom!

What makes you say that?

A 3-slot 4870x2 in PCIe2 and 2-slot 4870 in PCIe1 looks fine to me? although airflow could be a bit of an issue.

Did't think of doing that way sorry , they wil fit but yeah your right airflow will suffer, i had xfire on this board in a antec 1200 geting a 5870 instead as there just no room for the cards to "breath"
