Ok, so I'm looking to upgrade the pc I built recently and I know the things I want, but I don't know the order I want to buy them in. I'm looking to get 8 more gigs of ram, (I currently only have 8 gigs) I'm looking to buy the corsair k70 cherrymx red, (which is an upgrade from my old garbage membrane keyboard) I'm looking to buy a 500gb ssd to replace my hard drive as the boot drive, and last but not least, I have a gigabyte r9 290 windforce graphics card, and my motherboard can support dual gpu so I thought another r9 290 down the line will be pretty good. What do you guys think the order of purchase should be for these items?
