try buy some 3m thermal tape for the swiftech ram sinks, the original tape are lousy, fell of from vga ram easily... i experienced before also, after replace the thremaltape, problem gone...

sishh i know that way before u and he did.
infact i tried it before he did.. with a 8800 ultra and hd2600XT..

i am talking about 9800gx2..
sishh
on 3870 crossfire u cannot do dual monitor on crossfire
on reference 3870x2 u cannot do dual monitor on crossfire
on any 8800gt/gtx/ultra/gts on sli u cannot do dual monitor

but...
on asus hd3870x2 with both gpu enabled in CC and on Crossfire  u can do dual monitor.
so thats y i was hoping the 9800GX2 was possible..

sishh.
