Hi, I own a Tyan S2390/Trinity KT motherboard and wish to install a 3d graphic card based on the Radeon 9700 but I am being told they probably aren't compatible.I read that AGP cards are usually backwards compatible with older AGP slots. I wonder what could be the issue and what recent 3d card shoult work if any?

Specifications - Chipset/Core Speed: FireGL 9700/325MHz Memory/Effective Speed: 128MB DDR/620MHz BUS: AGP 1X/2X/4X/8X Ports: Dual DVI connector Support 3D API: DirectX®9, OpenGL®2.0 Cable/Accessories: 2 VGA via DVI Adapters, Power Cable, 2 CD Max Resolution@32bit Color: 2048X1536@60Hz

but how about that: Motherboard TYAN S2390/Trinity KT Card Model: 8363-686A BIOS Vendor: Award Software International, Inc. BIOS Version: 6.00 PG BIOS Release Date: 09/14/2000 BIOS Properties: Plug and Play, Flash, AGP AGP Capabilities: Revision: 2.0 Rate: 1x, 2x, 4x Aperture Size: 64 MB Sideband Addressing: supported (disabled) Fast Write: not supported CPU AMD Family: Athlon(tm) Internal Clock: 909 MHz Internal Clock Maximum: 909 MHz External Clock: 100 MHz Socket Designation: Slot A Type: <unknown> Upgrade: Slot 1 Capabilities: MMX, CMov, RDTSC, 3DNow!, Extended 3DNow! Version: AMD Athlon(TM) CPUID: 0x00000642 Total Physical Memory: 384 MB

So, from those two specs, it appears that it will work. Running 3 cards is another matter.
