VikingSOS :
Do you have any more advice like SSDs?
I think that SSDs are great and are a good addition to any mid-high range gaming build, but for a PC like yours, it's simply not worth the money. I'd focus on things that directly affect performance of the PC, like processors, RAM and graphics cards.
My suggestions to you:
Step 1: Sell the HD 5450. I just sold mine for £20 on Ebay.
Step 2: Buy and install an AMD A8-6600K processor.
Step 3: Buy and install an extra 4GB of RAM.
Step 4: Buy and install an R9 270 or GTX 750Ti, depending on wattage of power supply.
In total, these will come to around £190, considering the money from the sold 5450. I'd upgrade the things in this order, to get the best performance out of your build. It's not that much money in the long term!
Hope I've helped.
