I'm getting some parts for free off my sister boyfriend. I'm having 4x 4gb corsair vengeance ram. Amd fx 8350 cpu . MSI 970 motherboard and a cooler master fan. I have around another £500 to spend on parts. Just asking for any parts to add or replace from the pc . I would like the PC to contain an ssd to improve overall running speed. Just give me some advise to on what to replace and what to get.
