I've also got a 530, and I upgraded it a bit this year. I already had 4GB of RAM, but I upgraded to an AMD Radeon HD 6570 1GB (around $60) which is the fastest video card I could find that would work. And, I upgraded to a Core2Duo E8500 3.16GHz CPU (around $60) which is the fastest CPU I could find at the time. If you ever decide to upgrade your CPU, you have to check and see if your 530's motherboard will support quad core or not. Mine won't. I also picked up Windows 8 while it was on sale. Anyways, the computer runs much faster now and boots up a lot quicker too. I've been playing Skyrim on it lately at a graphics level comparable to an XBox 360. I haven't checked to see what framerate I'm getting on it, but it feels smooth to me.
