I want to upgrade my G20BM very much, but for the prices of the components, I'm not sure if I should just purchase/build a new computer. I want to upgrade my cpu, gpu, and RAM. Obviously, RAM isn't as expensive, but I'm more worried about the CPU and GPU and what is compatible with the BM. I want to increase my dedicated VRAM from the 2gb stock to either 4gb or 8gb, and increase the processor speed from the 3.5 to 4.0 with possible quad core or 8 cores to handle the programs I run while gaming (desktop recorder and voice chat) Any help and suggestions are appreciated!!!
