Departed 6R LAX for the GARDY3 Departure. Before takeoff we advised Ground that it was questionable if we could comply with the 8;000 FT restriction at TRAAP. We again advised LAX Departure of being [unable] to reach TRAAP by 8;000 FT and they told us to do the best we could. The FMC placed us just past TRAAP at 8;000 FT. On departure we had moderate turbulence in the climb; a heavy aircraft with restricted performance and possible wake turbulence from the B777-300 that departed before us. Approaching TRAAP with climb decreasing to 300 feet per minute with degrading airspeed; then followed by a strong uplift with 2000+ rate of climb. We passed TRAAP above the 8;000 FT restriction. Heavy aircraft with decreased performance. Moderate turbulence with associated weather. Wake turbulence from aircraft in front of us.

B777-200 flight crew reported overshooting an altitude restriction departing LAX on the GARDY3 SID; citing weather and a wake turbulence encounter as contributing.
