Judging by the CPU, it "may" be upgradeable to a 460M. Yet, I would not recommned upgrading unless HP offers the solution in a similar laptop, that have identical exteriors. Check if the laptop has MXM Type III B, thats the standard for laptop GPUs. Also, chack to make sure if the quadro 880m supports TDP of 75W, which is what the 460M, 470M and 5870M (also anything lower) support. Note, your motherboard may not recognize the card, so its your risk.
