I broke a 5000 Score in Valley Bench - Not too shabby for a 1st session 2 Reference 290X's under water.
2 OEM R9 290X's in CF under water in using TRIXX in synchronized cards in Multi-GPU config set 1130 x 1500 x 143 x 50 MAX Temps where VRM 40C and GPU 46C. XSPC Blocks through a Coolgate 280x60x140 Rad with 4 Noctuias in push/pull and an RP 401X's2 with 2 PMW400 pumps in series. The i7 2700K has a Corsair H110.
Might do a little better if I tweak the cards separately.
One Card is a Ref Gigabyte and the other a reference Sapphire with XSPC blocks - i7 2700K on an Asus P8Z68Pro-V Gen3. Fractal Midi ARC R2 Box and an XFX 1050W Black Edition BEFX KM3 PSU. 16GB of Samsung Green running at 1866 Mhz 9-9-9-24 1T 1.35v.
Love that Fractal ARC Midi R2 case but man she's getting heavy.
Believe I scored around 2970 for one card and 4600 in CF under air and approx 3500 for one card under water.
