[QUOTE="ShadowDeathX"]So should I buy another 7970 for Trifire or get one of these babies and Quadfire? Decisions. Decisions.Elann2008
Is it me or does Tri-Fire scale very well? Very few benchmarks out there to go by. If AMD can tap into the power potential with excellent drivers like they have been saying since January, it could be a very good thing.
I heard of the dread blue screen for tri-fire multi-monitor setups since last September. Â Not sure how things are now but I'm sure you could look that up. Â
Real world power consumption for 7970 tri-fire.

The Test Rig:Â (For power consumption reference)
- ASUS Maximus IV Extreme-Z
- i7 2600K @ Std settings
- 3x AMD 7970HD in Tri-Fire @ std settings
- 2x 240GB OCZ SSD's
- 3x 1TB Velociraptors
- Corsair Vengeance 8GB DDR3 @ 1866
- XFX 1250W PSU
- 1260 & 360 Radiators fed with D5 pump
- A few lovely lights... lol
Results as follows:Â
(All settings maxed for each game, using eyefinity at 5760x1200)
Benchmarking:
- 3D Mark 11 (Performance) 880w
- Heaven 2.5 898w
- 3D Mark Vantage (Performance) 906w
- Furmark on 3 screens 908w
- Aida 64 stability test - 1092w
Gaming:
- Mass Effect 3 - 565w
- Shift 2 unleashed 570w
- Syndicate 580w
- Skyrim 620w
- Hawx 2 641w
- Alan wake 720w
- Crysis 2 780w
Triple GPU setups scale well. The problem most of the time is Quad GPU setups.None the less, if I get a third 7970 or a 7990, the dreaded AMD frame time problem will go bye bye.
I'm going to have to upgrade my power supply. I think 1300 watt power supply is good enough for three 7970's or 2 7970s + 7990.
