Assuming you have sufficient "reasons" for a purchase decision, you should also consider the high Recommended System Requirements for Oblivion, and be certain you meet them. If you aren't really a Gearhead type of hardware freak, you can run the tests to determine the status at

(Their test
can be confused by late model non-P4 processors from Intel.)
Here is the list:

System Specifications
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

(per the above pair, or "supported")
{and DirectX 9.0 compatible driver};
8x DVD-ROM drive
DirectX 9.0c (included)
DirectX 8.1 compatible sound card
4.6 GB free hard disk space
Keyboard, Mouse
The key components in my example list (below), all meet or exceed the Official System Requirements.
My personal gaming system had previously been used as an example, showing
all of its guts, so to speak, not just the key components (the double asterisks), but it's edited now to see if this will help you more:
