So I might as well give up? Because I'm not buying a new card for this.
Yes. Point.
Invest or leave it.
I just puchased 9 x 6990 for 3 mining servers. Decent investment. More to come.
Damn, and I felt good about my 4 x 6990s.
How will you be powering the 6990s? I had a Thermaltake 1500W and it wasn't enough for 3 x 6990s in one case.
