Hello again, I'm now pretty sure that I will end up gifting my CPU, mobo and cooler to my brother, or giving them to him for a very small, symbolic amount if he insists on it, so that this should mean no gain in budget for the main upgrade overall, but also mean that I don't really intend to build a secondary PC anymore, at least in the near future. So we could actually consider going over 600-700 euros a little bit if worth it.
Also, I would like to mention that I am currently in Germany, and returning to France on the last weekend of February, which leads me to think that I should probably buy my new CPU, mobo, SSD and cooler here in Germany and bring them back with me on my way home, seeing as prices in France are much higher (more than 20% more for the 10700KF for instance). That would mean that I'd end up buying everything in 3 or 4 weeks. I've mostly been looking at Alternate for prices but feel free to recommend any other retailers that are worth checking out.
For the SSD, I've been looking at the Mushkin Pilot-E 500 GB, as suggested by the guide you linked to me, which is at 65 euros on Alternate.
For the CPU, well it's not that easy to choose. I think I'd lean towards the 10700K rather than the 5600X simply because of 8-core performance in editing, but at the same time since I'm no professional and don't intend to be one, would it really be worth it in terms of trade-off for the single-core performance in games ? Is 8 cores more "future-proof" (if that even means anything with how CPUs evolve) if my main use remains games and editing for the coming years ?
I would go a bit over budget and buy the 5800X with my eyes closed considering it pretty much solves the single/multithreaded tradeoff problem, if only the huge price premium (+150 euros on Alternate compared to the 10700K) didn't seem so undeserved. Is there any chance of it becoming more reasonable in Germany by the end of February ? Or even reasonable in France in March or so ? Is it worth waiting ?
I was going to start talking about overclocking, mobos and coolers initially, but I suppose we should settle firmly for a CPU before doing so. At least the part about reusing components or not is sorted out.
