Hi there, new to forum so this is first post. I have an acer spire T180, stuffed 4 sticks of ram in it, a better graphics card and on a performance rating the GPU is letting the side down. It's on a MCP61SM-AM board with a AMD 64x2 Dual core 4200+ 2.20 GHz. Can anyone recommend a better upgrade CPU for this board? The machine is used as a home pc and online games machine. Thanks
