I'll briefly introduce myself before asking all sorts of questions, i'm everyzig, 28 years old, been playing KSP for about a year, and i hang around the KSP subreddit quite a bit (same name) Now i started out playing KSP on my work-laptop, which i have had to turn in, since i switched employers. I've since constructed my own KSP rig, a tiny mini-itx computer made up off scraps from the attic (case, SSD), leftovers from upgrading my PS3 (HDD) and some fine parts supplied by the lowest bidder, in good kerbal traiditon (Asrock H61m-itx, Intel G1610, 2x2gb ddr3). Now i'm slowly getting more funds available for kerbal purposes, and i and itching to upgrade. CPU wise the celeron does OK (my launchers tend to be 200 parts MAX), but the integrated video is struggling with my 1080p screen, even at the lowest settings. So my question is, what kind of GPU would i need to run KSP at 1080p, high detail, full res textures and with some mild AA? To be blunt, i want an Nividia card (my rig runs linux, and recent encounters with AMDs linux drivers have convinced me to stay away), and if possible, i'd even want a low profile single slot card (as this allows me to keep my machine in a much smaller case, i have my eye on an Antec ISK-300, which is already larger then what i have now), but that would mean GT640 or lower, and i have no idea if that is powerfull enough. KSP is pretty much the only PC gaming i do, and my proposed upgrade would also include an i3 cpu, a new case and a new PSU, so anything more expensive then a GT650Ti is out of my budget Anyone have any experience with the GT630, GT640, GTX650 or GTX650Ti in KSP?
