What can I expect from a 1000 EUR PC?

[thl]

Hi Folks,
playing with PhotoScan standard and dont like to spend so much money at the beginning, I am wondering what I can expect for ~ 1000 EUR. I understand that GPU cannot be fast enough and RAM cannot be much enough.
Currently I am playing on a PC, having 16 GB of RAM and this is the maximum, while runs start crashing when I add more images.

Does anyone have a suggestion for a configuration which is worth it's money?

Thanks for any suggestions.
