I ordered a laptop for using as a field monitor and DVR using Adobe's OnLocation (DV Rack) with the Quadro FX 2500M graphics card. At the last moment the builder says the Quadro is not available (or he can't afford it) and can only offer the NVidia 7950GTX or dual 7950 GTX SLI. Can anyone please help me decide whether or not to accept either one of these alternatives?
