Thanks!
hi, get H61DEL
this have 1 x16 + 5 x1 PCI-e slots
That is extremely trivial to the GD65. It can hold 8 cards and your H61DEL can only hold 6, and 5 slots need powered risers. The GD65 only needs 4 powered risers for its x1 slots.
why do people still spread this powered riser FUD? I have NEVER used a powered riser, and I have never had problems. All my rigs have 6 cards (8 gpu for 5k series, or 6 7970) and use 16x and 1x slots all with 1x > 1x risers. Been mining since july 2011.
Do you mine SHA 256 or scrypt? If the latter then powered risers help to feed the memclock necessary to hash on scrypt. SHA 256 coins don't need this extra power for the memory.
