So i'm rather new to PC gaming and my friend just bought a new Alienware, and decided to give me his old M9700 since he wouldn't be using it before. I know it's really outdated, but I also know it can run a decent amount of games. And i'm not really looking to run everything at max with it or anything. I has a 150W adapter, and I don't really know how the wattage effects the gaming, would that hinder anything? I was planning on upgrading the graphics card, and maybe the processor to a better dual core than the Turion 64 x2. If this isn't the right place to post please let me know, I'm new to the website and the PC gaming world as a whole, so I'm not exactly sure where to turn.
