What's the fastest 2x AGP card?
Just wondering what the best graphics card is that'll work in a 2x AGP slot. I have a dual 500 on order and the current card is a plain Radeon 32MB AGP. I'm sure it's fine for most things for now, but it would be helpful if I knew what my upgrade options were for the future.
Also, I believe that newer cards will not work with older AGP speeds... this is true? You can't just put a 4x AGP card into a 2x AGP slot and get it to work (of course with lower performance), correct?

Remember, 4X AGP cards are backwards compatible with 2X AGP. Similarly newer 8X AGP cards like the Radeon 9700 are backwards compatible with 4X AGP, but not 2X.

ATI disagrees:
[quote] System Requirements
*\tIntel® Pentium® 4/III/II/Celeron?, AMD® K6/Duron?/Athlon®/Athlon XP® or compatible with AGP 2X (3.3v), 4X (1.5V), 8X (0.8v) or Universal AGP 3.0 bus configuration (2X/4X/8X).
*\t128MB of system memory
*\tInstallation software requires CD-ROM drive
*\tDVD playback requires DVD drive<hr></blockquote>
Needless to say even assuming a Radeon 9700 can go into an AGP 2x port it is going to have a serious bottleneck in the bandwidth. It is really designed to take advantage of the full 2GB/s. That said the performance gains aren't linear.
I would say probably Radeon 8500 or 9000 PRO is the best for an AGP 2x port.
