Again I think we are seeing saturation

Look at the diagram.

Data from drive is 2G/sec
Processor 10.6G/sec
Video 16G/sec
Ram 6.4G/sec X 2 for ddr2

Use of two video cards, reduces the video bandwidth 1/2.

I mean you have this 16G/sec video buss but nothing that feeds it that fast. Your ram is 12.8 and hard drive 2.0 ....

You just can't get the data to the video cards fast enough. More ram on the video cards I say. I would dump the two you have and get a single 1G card.

Of course you have low cpu usage as the 2g/sec is the bottleneck when you have to get textures to the video card.

Just look at your hard drive light when your framrate drops, if its blinking fast well there is yur problem.

Well here is the i7:

The I7 goes at 3 X 8.5 on all 3 busses, cept the hard drive is still 2g/sec .....


You need to keep textures in system ram or add video ram, or both.

If system ram is not holding textures then its not doing any good ....
