Last week-end I started to play this great, new game! I've logged like 90 hours gameplay already! Just can't stop iterating.. To get to the point, with my current two year old AMD build, the game lags a lot. I have been reading, and people say the physics demand a lot of processing power. I've fallen so much in love with building rockets, I've decided to construct a computer in the same sense. i.e. I want to cram as much power as I possibly can into it, but still fly (bang for your buck). I will mainly play KSP, some LoL, some DayZ and rarely WoW. I never play them all at the same time, so hard drive space isn't an issue. For entertainment I have several HTPC's with larger hard drives placed around my home. So this is about helping me build a computer for around £1k that is optimized for KSP. I've already put together something I think is quite powerful for the money spent. I just need advice if I should go for better processor, but also step down on the graphics (to keep budget). As mentioned before, it's mainly about how it would run and perform in KSP, however I wouldn't mind a stunning world in DayZ either.

(Generated by PCPartPicker 2013-06-26 21:11 BST+0100) Notice I couldn't find the evga 760 in the list yet, so it will be more expensive. Also my choice for PSU is the 'be quiet! 530 80 bronze' which is more expensive. Currently this build costs 980 GBP with the lowest prices i could find that ship to Stockholm, Sweden. Is there anything i can do to further optimize my experience, performance wise, in and around this budget?
