Required video card for gamecube

[Guigui4731]

Hello all,

I have Dolphin 5.0 on my computer, I mainly play to GC games like Mario Kart.
With my actual config, I can play single player without Any issue. But when playing 2 players, The game slows and it is very uncomfortable.

My config is the following one:

Win7 home premium 64bits
Intel i5 4570 3,2GHz 6Mo cache
Intel hd graphic 4600
8Go RAM DDR3 1600 MHz

I think I need a video card but I don't know which one I have to choose.

Is a card like ASUS GeForce GT710 1Go is enough to run most of GC games? Else, what should I choose?

Many thanks
