AGP express, slow down PCI-Express?

[Chris2wire]

Hi,

I want to upgrade from my regular agp board to a pciexpress board. I was wondering, for budgeting reasons, that perhaps I could upgrade to an agpexpress/pciexpress board and buy the pciexpress card later, and use my 6800gt for now.

My question is, will the architectural build and structure of having agpexpress on the board cause a slow in down for the pciexpress, when it is used after card purchased, as opposed to a board dedicated only to pciexpress?

Addiitonally... Im using an Athlon 64 3200+ .09nm core 939 cpu... Does this mean any newer amd skt 939 board should work with my current cpu?

1. Agp is controlled by a separate chip than the PCI-e, so no slowdown will happen. If you try and use a AGP graphics card and a PCI-e graphics card at the same time, your bios and OS will probably become confused and slow/shut down, but one OR the other should not affect speed.
2. Your CPU should work with some of the newer boards but I would check each board's web site for a CPU compatability list, there may be a conflict with your mainboard liking one type/brand of RAM and your CPU liking another type/brand.

If you're not planning on doing any extreme overclocking (and maybe even if you are, if you're willing to do a bit of modding) - buy this. It's really the only decent combo AGP/PCI-E board that exists. I'm using an AGP 6800GT in mine, and performance is great - and later when I have the money, I can upgrade to a new PCI-E card. AnandTech did a review of the board several months back, and found that AGP/PCI-E performance was among the best, in contrast to some of the other "AGP-Lite" or "AGP-Express" solutions that other boards/chipsets have implemented.

yeah, that asrock dual-939 is the way to go because it has a true agp slot. you're talking about those ecs mobos with agp-express right? it won't slow it down because the architecture isn't any different, they just modded a pci slot to become agp...so it's really slow agp, but won't affect pci-e.
