It's for a laptop and I was wondering if it would be better to upgrade it still using a single core? Or should I upgrade it to a dual core? I mainly just want to upgrade it so that I can run better games. And if I did upgrade the processor, would I also have to upgrade the graphics card? Even if I don't care if I have bad graphics? My graphics card is Intel(R) HD Graphics 3000. Please help me answer this question, for I really want to start playing better games then I'm playing now. And if you have any questions please ask. I will be checking up on this frequently. Thanks to whoever helps!!!
