The original system requirements are:
Operating System: Windows 98SE / Me / 2000 / XP [XP recommended]
Processor: Pentium III, 700 MHz [Pentinum 4, 1.4GHz or above recommended]
RAM: 128 MB [256 MB recommended]
Graphics Card: Direct3D compatible, 3D graphics board, minimum 32 MB VRAM [64 MB recommended]
HD: 1.5 GB
Sound Card: DirectSound compatible
DirectX: DirectX 9.0b or above
Internet Connection Speed: 256kbps minimum recommended
I believe the Radeon 7500 had 64MB of DDR SDRAM video memory, so it should be fine in that aspect. The only hangup might be the directx 9.0b requirement. The Radeon 7500 only fully supports up to directx 7. IIRC it supports some directx 8 features but not all (eg. no support for pixel and vertex shaders in dx8.) I would definitely give it a try though. It may run just fine with that card
