Hello I have a HP dc7900 CMT running Mavericks. It has three 1Tb drives, 8Gb ram and the stock HP dc7900 CMT motherboard, the on board graphics card is the GMA 4500 which I have working in 1024 x 780 resolution(the only resolution option). I Would like to get a new Graphics card at least 1gb I know of two that are compatible with the hardware but not sure if these are compatible with the mac OS.
Or if anyone has any better options that would work with the mac os than the two above please let me know.
Thanks in advance!
