I have decided to stay with my rig that has AGP 8X and not go for a board with PCIe. I can't remember where I heard or seen this, but there may soon be an AGP version of the Geforce 8800. The card I have does very well. But, like alot of people, we always crave more power. The XFX 7600 GT card I have is in fact a PCIe GPU on a AGP circuit card. Anyhow, the question I have is this:
If the AGP 8x bus has a said throughput of 2 gigs a sec,
is my 7600 GT 580M 256MB DDR3 utilizing that full bandwidth
of the AGP 8x bus? Is there any programs that would tell me what
the bus throughput is. I'm wondering if it is sending at the maximum
bandwidth, therefore not really being worth upgrading to an AGP version of the Geforce 8800 when and if in fact it ever comes out...
I don't think a 7600GT can come close to saturating the AGP bus in current games. For fun, set your AGP to 4X in the bios and bench your games with fraps. You may find the 7600GT rarely if ever is saturating AGP 4X. When I did this with a 6800U OC, I found that 4X AGP barely showed a 1 fps difference in most games at the settings I found playable on the 6800U. Given how the X1950 pro trounced the 7600GT, 7800GS, X850XT, etc, and that it kept up with the PCI-e version it's clear that the AGP is not limiting the 7600GT or rarely the X1950 pro for that matter. http://www.firingsquad.com/hardware/powercolor_radeon_x... http://www.tomshardware.com/2007/02/01/agp-platform-ana...
