Leistungsproblem 8800GTS - Hilfe!

Hallo Leute erstmal!

Ich bin absolut ratlos und ich habe echt ein ziemliches Problem! Zuerst hier mal mein System:

AMD Athlon 64 X2 6400+ Black Edition
Asus M2N32-SLI Deluxe
4 GIG Corsair XMS2 PC800 RAM
Gainwar Bliss GeForce 8800 GTS 640 mb
Netzteil 600 Watt von Thermaltake Toughpower

OS: Windows Vista Ultimate 64 bit


Ich habe bei 3dMark 06 gerade mal das folgende Ergebnis erzielt:

Main Test Results

3DMark Score 5901 3DMarks

SM 2.0 Score 2394 Marks

SM 3.0 Score 2304 Marks

CPU Score 2426 Marks


Detailed Test Results

Graphics Tests
1 - Return to Proxycon 19.428 FPS

2 - Firefly Forest 20.477 FPS

CPU Tests
CPU1 - Red Valley 0.762 FPS

CPU2 - Red Valley 1.236 FPS

HDR Tests
1 - Canyon Flight (SM 3.0) 24.528 FPS

2 - Deep Freeze (SM 3.0) 21.557 FPS

Des kann doch bei dem System net sein!!!!! - An was könnte das denn liegen?!?! Ich vermute, dass mit der Grafikkarte was nicht passt... Ich habe mein System schon mehrmals komplett neu aufgesetzt - verschiedene Grafikkarte-Treiber versucht und, und und....
