This are difference between 3x GTX285 --- 2x GTX295
3DMark Vantage, Performance:
28014 --- 32581
3dmark Vantage, Extreme:
16287 --- 15139
Crysis Warhead, 1920x1200, fps AVG (8XAA)
--- 56 fps 83 fps
Crysis Warhead, 2560x1500, AVG fps
--- 25 fps 1 fps (!)
Far Cry 2, 1920x1200, AVG fps
--- 110 fps 168 fps
Far Cry 2, 2560x1600, AVG fps
--- 75 fps 90fps
Stalker Clear Sky, 1920x1200, fps AVG
--- 70 fps 73 fps
Stalker Clear Sky, 2560x1600, AVG fps
--- 50 fps 55 fps
High AA / AF test, Far Cry 2, 1920x1200, 8xAA, AVG fps
--- 109 fps 120 fps
Conclusion:
2x GTX295 is preferable over 3x GTX285!
Advantages of 3x GTX285
1.) slightly smoother gameplay
2) Superior frame rate's at higher resolution's
3) More Ram
Disadvantages:
1.) currently pay a little more
2) For air cooling, 6 chassis slots needed (Quad: 4)
2.) 3 PCI Express slots are needed (Quad: 2), therefore Mobo selection smaller, almost always no extra physics card longer possible
Future speculation:
Unlicensed benefits by TRI-SLI, because drivers could possibly begin the 3th Better use of GPU
What is faster in the end, will depend on:
1) the drivers
2) the Overclocking potential:
The base of 285 cycles are 12%, 18% and> 20% higher than the base of 295 cycles!
At the core may also include a tool 295 with over 700, which means The 285 would have 850 to keep the distance between them.
It may therefore well be that the RELATIVE overclocking the GTX285 could be better than then or RELATIVE overclocking the GTX295, which means that the above scores could be even more closer and / or a slight plus for tri-SLi could arise.
Much will be the two solutions do not, this much is clear.
