Video Performance Decrease?

My question has to do with the 3DMARK2001SE Benchmark test and my recent upgrade to a P4 platform.

My previous machine was the following.

P3 866Mhz CPU
512Mb Crucial Cas2 133 sdram.
GForce 4 Ti 4600 (Nvidia 3082 drivers)
3dmark benchmark 6900.

Switched to;

P4 Motherboard with 533FSB capability.
1.7 Celeron with 128cache on board (400FSB).
1Gb of Cas3 133 sdram.(My board has Sdram OR DDR ram capability, either or only)
Gforce 4 Ti 4600 (Nvidia 3082 drivers)
3dmark benchmark 5300

What is the reason for my large decrease in video performance? Is it the 128k Celeron cache? Is it the fact that my memory is now decreased to 100mhz instead of 133 because of the Celeron FSB being 4 X 100MHz? If this is the case would getting the P4 2.53ghz CPU solve my problem? Or would switching to DDR memory be the quick fix? Maybe its something else and if so what?
Really like to know.

You don't have the right forum. You might want to try posting this in the Video card and monitors forum, or maybe the general hardware forum. This forum is for: "Have a question about the site, forums, or the SF team, and want it answered? Post here"
