well.. I am on a amd 965BE, radeon 5850 1GB... but that wasn't really the point.
I remember seeing in Tom's a whole analysis of games in which they would find where the bottleneck is on each game... but that happened before skyrim was released.
For example, I upgraded once my video card in an attempt to run Dragon Age smoother... and it was the opposite way, it wa slower... and later when this analysis showed up, they said that Dragon Age bottleneck is in the CPU, if you put a faster card, it will lag in CPU trying to keep up with it.
so I was wondering for Skyrim, if I could only upgrade either Vcard or CPU, which would be the best chance for increasing performance a bit.
