What can this card do? eVGA e-GeForce 7900 GT KO PCI Express

Yes the 7900GT KO should be able to play both of those on high, but have you considered purchasing the ATI Radeon X1800 XT? It's priced similarly to the 7900GT, performs better, supports OpenEXR HDR and Antialiasing simultaneously, high quality anisotropic filtering that is not angle dependant, and nice AVIVO features.

it will eventually get another one to sli with

it will run great for a few days....then it will start artifacting like crazy. Soon followed by crashing programs, blinking desktops, and finally BSODs whenever a 3d program is launched. The 7900 series is severely problematic!!! If you dont believe me go check evgas forums. I would go ati if I had the chance again.

Yeah there are definate issues with the 7900GT OC models, but evga would make good on a replacement if that's the case.

7900GT will not run 1024x768 max in Oblivion very well, it all depends on your definition of High. I think you will find Oblivion very playable at 10x7 on a 7900GT, but don't be surprised if you are tweaking grass distance, shadows, etc. because of some low fps in outdoor areas. Not sure in the end if you'd call that High details and be completely satisfied. Oblivion just hammers the GPU and for that game the X1800XT is the better choice.

All I have to go by is Firingsquad averaging 23 fps in their foliage test at 10x7 max, and Anandtech averaging 21 fps with a low about 12fps in their gate benchmark at 12x10 and their defintion of high settings. So clearly IMO both of those settings are above a 7900GT's playable range.

For Oblivion, consider a X1800XT and adding extra 1gb of RAM. Your CPU is still good. 1gb of RAM can bottleneck you if you have a 7900GT or X1800XT.
