About 3 years ago I built my first PC. I don't have any formal training, but found it to be an excellent project. I have noticed frame rate issue in games that are even a few years old. I want to know what the best way (hardware/software) would be to upgrade my graphics performance. Below are my current specs. Please let me know what other information would be helpful in determining how to optimize my system without doing a complete overhaul.
Windows 7 64-bit
Processor: AMD A10-7700K APU with Radeon R7 Graphics (just using heat sink that came with APU)
Memory: 2 x 4GB Corsair Vengeance Pro Series DDR3 2400MHz
Motherboard: MSI A88X-G45 Gaming ATX DDR3 2400
PSU: Cooler Master GX II - 75-W 80 Plus Bronze (not fully modular unfortunately)
Case: CM Storm Scout 2 Mid Tower
Thank you in advance for your help. I should note that I don't have an immense amount of very technical knowledge, so any explanations with a bit of background would be much appreciated for my own learning.
