Oblivion Graphic Requirements, How come they don't work for me!!! Options

[HyPN0]

OK, i would like to post my config first:

Monitor: Dell E176FP
Graphic Card:Ati RADEON X600
Processor:Intel Pentium Dual-Core 3Ghz
RAM:1024 MB RAM at 533 Mhz
Motherboard:Intel

To be more precise,it's DELL Dimension 5150 configuration......

So i simply MUST ask:
How come that i must play onlivion at 800x600 resolution,no AA,Low details,no bloom - And it still sometimes doesn't work properly!!!!Especialy when there are more NPC\Monsters on screen.

So i ask:How is that posible?I have Recommanded requirements and i can't play it on minimum!
My only guess is that this monitor is a piece of junk:Does the fact in can max support 75Hz refresh rate totaly change things?

Or some settings are badly configured?

Please Help

I seriously doubt that you'd get a firmed PC without some version - evne some older version - of graphic card drivers that just doesen't sound right...
