I've looking to build a system witch I'll be using to creating DVD/Blu-ray disk from Elements 10. I'm looking at a GeForce GTX 560 TI with either a 1GB or 2GB of memory. Does the amount of memory on the video make a difference?
If the price difference is neglible, I would always recommend more vram. If you get into more advanced software, like Avid or Maya or After Effects, even 3DSMax the amount of video RAM will have a huge impact on performance. At this time, for gaming 1GB is enough. 1GB is plenty for home editing and transcoding, too. But 2GB is more "future-proof" if there is such a thing.
