Oldblivion, Oblivion, graphics card?

My specs are:

3.0 Gig HT CPU

1024 MB RAM

5500 GFX Nvida, 256 mb card

80 GB harddrive

Which is better, Oblivion on low/ultralow graphics setting or should I get Oldblivion?

Anyone have Oldblivion? How much of an improvement is it?

Oldblivion will not help at all really. The purpose of that program is to allow Oblivion to run on cards that do not have DirectX 9, but yours does have DirectX 9 so it would really make no difference.

Oldblivion and Oblivion are the same thing.

Only in Oldblivion, you can run it on DX 8 or older cards, as long as they're powerful enough.
