G8x (your videocard as 8600M GT) has up to OpenGL 2.x/3.x support but OpenGL 4.x requires Fermi (GF 400- or 500-series) or newer card. lool

I can't test because this program connected to server - loop running Win 7 x64 SP1. :SOk. Problem found is EVGA PRecision or MSI AfterBurner running. This tool closed solved my problem! But Windows 7 may be abnormal and I will format HDD soon.
Now, I can download but on past sunday, NVIDIA may have problems.I tried to choose "Core PhysX SDK", "APEX SDK"... and to click button "Agree & Download" but I can't download because click this button -- loops. :Sthe loop happens if you forget to login
But I got no more than and always 30 fps (CPU AMD X6 1055T@stock) but maybe this performance may be capped.I confirm ~32 fps capped, after upgrade from AMD X6 1055T to Intel i5-2500K.
With latest R326.98, ShaderToyMark runs fine on Win7/Win8 with correct FPS.Yes, STM and FurMark work correctly for framerate and temperature despite abnormal performance (STM only) because the framerate by and temperature by Geeks is same number to monitor eVGA Precision.
Sorry but I don't have anymore a WinXP testbed so I can't tell you if ShaderToyMark still works or not correctly with XP.
Does your GTX 480 work fine with FurMark (correct FPS, GPU temperature)? If yes, forget your issues with ShaderToyMark.
