Zum Schluß nochmal zu den MTRR's. Probier einfach mal, mit Sysbench bei DIVE die VideoBusBandwith zu messen. Wenn Du da in den Bereich über 1000 MB/sec kommst, hast Du kein MTRR Problem.
Hallo Holger,
vielen Dank für Deine Tipps! Ich habe vorhin einmal folgende Tests mit Sysbench durchgezogen (ich habe die Test jeweils mit 4 statt 6 Kernen gefahren):
1. Komplett Systemest mit GeForce 6600, Ergebnis: (die Disk 39.3 am Schluss ist übrigens der USB Stick)

Bemerkenswert ist für mich, dass die ATI zwar im PM Graphics Mark 718.777 zu 479.395 Punkte fast doppelt so schnell wie die 6600 ist, beim DIVE aber fast um die Hälfte unterlegen 1449.835 zu 2700.628 marks.
Leider leider leider hat die X800T noch einen entscheidenden Nachteil, den ich zwar irgendwo noch im Hinterkopf hatte aber wohl verdrängt habe: Dos und Win-OS2 läuft nicht im Fenstermodus
![Traurig :(](./images/smilies/icon_e_sad.gif)
was gleich den wunderbaren Vorteil des doppelt nutzbaren DVI Ausgangs (Multihaed!) gegenüber der 6600 (nur VGA) zunichte macht. Ich muss also weiter suchen nach der Grafikkarte, bei der sozusagen unter SNAP alles geht, inklusive DOS und WIN-OS/2. Die sonstigen Daten zur CPU, Speicher und Festplatte vermitteln vielleicht schon einen Eindruck, wie schnell das System im Moment bereits arbeitet.
