ATI is the older company (1985) than Nvidia (1994). However there was a time, about 1999-2002, where Nvidia singlehandedly dominated the 3d graphic card market, ATI sort of "came back" from that, and is head-to-head with Nvidia today.

According to the Oblivion website you need to have an ATI X800 series, Nvidia GeForce 6800 series, or higher video card. Here is a list of supported video card chipsets. However you can still get the game to work if your card is not listed here. * ATI X1900 series * ATI X1800 series * ATI X1600 series * ATI X1300 series * ATI X850 series * ATI x800 series * ATI x700 series * ATI x600 series * ATI Radeon 9800 series * ATI Radeon 9700 series * ATI Radeon 9600 series * ATI Radeon 9500 series * NVIDIA GeForce 7800 series * NVIDIA GeForce 6800 series * NVIDIA GeForce 6600 series * NVIDIA GeForce 6200 series * NVIDIA GeForce FX series
I would reccomend NVIDIA but they are very similar.
AMD/Ati is its main competitor.

AMD/Ati is its main competitor.
ATI is a very respectable card producer, and they have excellent cards to choose from, but nVidia has numerous features and tweaks that ATI does not, and a considerable lineup to choose from as well. I would choose nVidia over ATI.
The NVidia is faster.
At what age you live in. If you asked this question 8-10 years back i would say no GFX is faster than this. Today's Most powerful Graphic cards are as follows:1. ATI RADEON 59702. Nvidia GeForce GTX 4603. ATI RADEON 58704. ATI Radeon 58505. Nvidia GeForce GTX 2856. ATI RADEON 4870 X 27. Nvidia GeForce GTX 2808. Nvidia GeForce GTX 2759. ATI RADEON 489010. Nvidia GeForce GTX 260and Nvidia Is launching GEFORCE 480 and 470

The software coordinating multiple monitors between the GPU and the OS differs between ATI's driver (where its known as HydraVision) and Nvidia's, (called nView) and both sets of code dislike one another vehemently.... If neither your integrated ATI or discrete Nvidia graphics cards has two monitor outputs, you should exchange the Nvidia card for a comparable model with an ATI GPU. If one of your current GPU's has two monitor outputs, disable the other card, and implement the corresponding multi-monitor mode associated with that graphic driver. ☺
