Probably the 150,000,000th Vid Card Question., I need a bit of help again Options

[Taillus]

Stop me if I am going crazy with this but I really want to make sure. Through work I am able to get an ATi X800 AGP 256MB Vid Card at a really good price. I know this card is listed on the "supported chipsets" in the FAQ's of their site but that is as far as my knowledge goes.

I have a 2GHZ P4 Processor
512MB of dual channel DDR ram
a Sound Blaster card (No idea what type)
and as it stands a P.O.S Nvidia MX 420 Vid card
Not to mention that I have updated just about everything I can possibly think of.

If I replace the vid card with the X800 stated above will I be able to run Oblivion? I really don't mind if I have to run it in 640x480 and with the bare bones settings I just want to play it like mad. Will this setup do until I have the extra cash to buy a Dell XPS system next year?

I'm running oblivion with an ATI x800XL 256MB. I have a faster proccessor though (AMD Athlon 64 3200+) and more ram (1.5GB). I think Oblivion is more video card dependant than morrowind though, and heres what kind of peformance i get:

I run with Bloom lighting (HDR is not supported) no AA, distance sliders nearly maxed and at a resolution of 800x600 I get very smooth framerates and acceptable load times. It also runs pretty smooth at 1024x768 but I think the mods im using are slowing me down some so I dropped my resolution to 800x600.

The only video glitch I have experienced with this card is when I run Anti-Aliasing and any nearby creature uses the chameleon effect, my framerate drops to a slideshow (1 or 2 FPS)

I am acctually upgrading to a Nvidia 7800 and installing a 150GB 10,000RPM Raptor harddrive though cause I just want Oblivion to run super smooth with nearly instant load times. =)
