I'm torn on which version to get.
I only have a 9800 PRO, which means the frame rate will probably suffer compared to the 360 version. After seeing how well the game looks with its high end visuals, I don't know if I can play the game with things toned down.
On the other hand, the PC version has the ability for a ton of mods and will be quicker with patches. Don't know if the 360 version will be patched at all. With a game as big as Oblivion, there will be bugs and glitches. It'll be nearly impossible to find them all before release. So if the 360 version will have same day patches as the PC version this would be good. Also, it would be nice to hear some confirmation where some of these PC mods making it over to the 360.
