yes its a reference card, 8gb. I average 125 with those two 480 and a 7950. with .6 its stable, once in awhile one card shows 0.00, but ever since redoing my bat file this morning its been stable all day with no issues.
here's my bat for the 480's:
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
