Re: Recommendation for Video editing/Gaming PC
If you have quality videos I don't know of a program that will utilize CUDA. You'd want to encode to x.264 so it's going to be dependent on the processor. A Sandy Bridge 2600K would be a better buy IMO since it has higher clock speeds. That would mean a different board and memory setup though.
Have an ATI card here. No real reason to complain about the drivers. Install them and forget about it. I don't feel the need to update them every month so that could be why they work better than if you constantly were switching them out. Would agree that there might be issues with certain releases, so the best thing to do is just figure out which releases were solid and stick with that.
