TLDR: Cpu and SSD upgrade on old system, any pitfalls? AMD Phenom I would like to upgrade my families home office pc, as its a bit sluggish. Its built around a AMD Phenom 2 x2 500 Socket AM3 (938) and the motherboard is a MSI 770-c45(MS-7599) version 1.9 the info I got from CPU-Z I'm thinking of upgrading the cpu to a quad or 6 core cpu, what would people recommend? I was just going to buy a cpu from ebay. https://www.msi.com/Motherboard/support/770C45#support-cpu shows that an AMD Phenom II X6 (1090T) is compatible , I think thats the most powerfull cpu I can get for it. (Its 125W, my psu is a newish Corsair 550W replaced a few years ago) so I think that will be the way to go. O and an 8800GT my old GPU Do you see any compatiblilty probs with this upgrade? Second upgrade is to add an SSD, reliability is the most important factor. I would like to copy the OS windows 7 Pro, over to it, The C drive partition is currently 250GB and using 150GB. Work is currently saved now on a separate hard disk and backed up I believe I need to get an SATA SSD for straightforward booting/compatibility purposes. and was looking at a Samsung 860 EVO 500GB 2.5” SATA SSD (5 year warrany) about £78+ Is it the write process that is damaging to the SSD? So if I install the OS on it, then the SSD is only being used for read purposes meaning its reliability will be much higher? And after install I make sure the Cach/swap file is off for the SSD and check that TRIM is on. What do you guys think? Anything I should check before hand or lookout for.
