Future PC Build - Is it good enough?

[artantaaa]

Dolphin needs CPU power more than GPU power. The best processor to use for Dolphin now is the 4670K. If you buy a $100 GPU instead of a $200 one, your budget would remain the same and you will get the best Dolphin performance possible. You could probably even use your old graphics card if its fairly recent, unless you want to run a useless amount of antialiasing.
