minimum specs: windows XP, 512MB system RAM, 2 ghz pentium 4 or equivalent processor, 128MB direct3d compatible video card and directx 9.0 compatible driver (availible for download though card manufacturers site usually) i know my video card is way below specs (radeon 300 or something ) and it works great on medium texturing
And I run oblivion fine, it doesnt look as pretty as it would on a 1000 dollar computer, but it still is pleasing to the eyes. Has its lag moments, but still doesn't make you go "UGH THIS RUNS SLOW" or anything.
Here are the official requirements and recommendations:
Recommended: • 3 Ghz Intel Pentium 4 or equivalent processor • 1 GB System RAM • ATI X800 series, NVIDIA GeForce 6800 series, or higher video card
Minimum System Requirements: • Windows XP, Windows 2000, Windows XP 64-bit • 512MB System RAM • 2 Ghz Intel Pentium 4 or equivalent processor • 128MB Direct3D compatible video card • and DirectX 9.0 compatible driver; • 8x DVD-ROM drive • 4.6 GB free hard disk space • DirectX 9.0c (included) • DirectX 8.1 compatible sound card • Keyboard, Mouse

I've found that the 700 and above range is neccessary on the video cards .. I have in the Geforce 600 range and I really get too much lag to play well.
