Hi, I want to buy a core 2 duo dell machine. The default option, which is what I will go for, is GMA 950 - could someone confirm is any of the following three options is FULLY (and easily!) supported?

128MB ATI MOBILITY™ RADEON® X1300 HyperMemory™ [add $49 or $2/month1]
256MB ATI MOBILITY™ RADEON® X1400 HyperMemory™ [add $99 or $3/month1]
256MB NVIDIA® GeForce™Go 7300 TurboCache

Thanks!
