I keep seeing this even on MLK, and I've been told plenty of times, again, also on MLK, for being an idiot for not doing it, but I just saw this great video about the PC disease known as hardware upgrading. I still remember all to well telling a member how to create a great rig and to get a GPU that is the best for its level, of which the next step would require more than just a GPU upgrade, meaning that for a 10 FPS gain, the cost is close to a couple of hundred USD. They went ahead and got a beefier card just because it existed. Same goes for Overclocking. How many people here on MLK do it just because they can.
So about PC gaming and hardware:
YOU DON'T NEED THE BEST HARDWARE. Even a mediocre rig can max out many games and run many others at a very reasonable and good looking settings. After all, console versions always run the same games as though on "low" settings due to hardware limitations. So about that video. Just watch.
