Hi there, I have an older computer. I have an ATI Radeon 5450, 8 Gigabytes of DDR3 Ram, an i7 2600 CPU, a Pegatron 2AB6 MOBO (Cleveland-GL8), and a 300 Watt PSU. When I first started playing lighter games on it (Minecraft), I was at least able to get 60 fps. Now, I can't even get 60 even with Optifine (helps boost performance for Minecraft). I recently downloaded CPU-Z to see what I had in my PC, and I noticed my GPU was running at quite low speeds. It is only running at 157 MHZ Core and 200 MHZ memory. I checked online, and it said the 5450 usually has around 500-600. Why has it gotten so slow? Also, I feel like my GPU is in need for an upgrade. Yet, my old BIOS is really limiting my choices for a GPU. It seems like the only ones that work is some of the older AMD/ATIs. I am not looking for huge performance, but I want better than I am getting right now.
