most laptops - Windows or Mac are almost un-upgrade-able. This is due to the GPU being integrated into the motherboard. Sure RAM is but that will only get you so far as you've experienced first hand. 32gb is massively overkill if your processor and GPU aren't up to scratch. Whilst MBPs are fine you will probably save some money if you go down the Windows route. Mainly because Apple skimp big time on their graphics card and mix and match intel chips with AMD gpu's. If you're running a lot of 3d or video work then an i7 with hyper-threading is the one for you. If you're just photoshopping and working in 2d then a mid range i5 will be perfectly fine. Again if you're trying to do 3D your GPU is most likely your bottleneck. Aim to get a minimum of 2GB or VRAM - 4GB would be ideal for future proofing. The lowest spec 15" MacBook Pro is £1600 and tbh the components are worth half of that.
Excellent advice, as you say RAM alone isn't enough, even scrolling through RAW files in LR is laggy and that's with a pretty clean install and programs running off the SSD.
