So this is what I was thinking based on the prices of the four parts in question (screen shot from HP parts store attached), but I am not sure that I can replace the screen or GPU.

I have two units to pick from and am having a breakdown deciding at both have their tradeoffs: one (V1Q02UTABA) has better graphics (Firepro W6150M) and worse screen (1600x900 TN at 220 cd/m2) while the other (X1X64UTABA) has better screen (FHD IPS 300 cd/m2) and seemingly worse graphics (Quadro M1000M) as well as + $125 price. Prime use: Photoshop Lightroom with hi-res data. I have a great external screen and color calibrator for pre-print processing and proof, but certainly would appreciate the opportunity to do quick retouching on the go. Thanks for any input.
