gollark: It's unusable at this point because the thermal paste has never been replaced, it has the old 500GB HDD it shipped with, and it runs Windows 10.
gollark: I have an ancient laptop around with a Core 2 Duo and... 210M or something?
gollark: I actually have a GT 710 around, since I needed a card which could do basic video output but didn't care very much about any actual gaming.
gollark: The GT 705 is Fermi, the 710/720 are Kepler, *some* 730s are Fermi and some are Kepler, and the GTX 745 to GTX 750 Ti are Maxwell.
gollark: The mix is very weird, actually.
