Graphics choice for tMPR 15"

[jemsurvey]

Sorry about title...typos.

Hey all,
Wanting to place my order today for the 15" tMBP but can't seem to find info on how the choice of the Radeon 455 or 460 will affect battery life. I do mostly Photoshop and Lightroom, no video, and will run Windows 10 with Parallels or Bootcamp. Will I see a significant drop in battery life with the 460 or will the 4 gigs of memory offset any negatives?

Thanks for the help,
John

Get the 455, not worth the extra $$ for Lightroom and photoshop, maybe Premiere if you did video stuff..
