Hello,
I need help. Can my motherboard: G41M-VS3 R2 support my graphics card: Radeon HD 6950? Do I have to remove the build in video accelerators and then install my graphics card?
Yes, your motherboard will definitively work with a Radeon HD 6950, since it has a PCI-E x16 slot.
And, no you don't need to remove anything, since the motherboard will simply disable them when they are unneeded.
