Having a 24 inch widescreen is a bitch. I can’t afford the video card that can play Call of Duty 4 with full detail at 1920 x 1200 (Nvidia 8800GT and an AMD Athlon 2x 5000+ not cutting it). So I started playing at 1280 x 800. Much better. Sure, the game looks a bit blurry, but the frames are much much smoother and I can track my opponents way more effectively. This isn’t quelling the cheating accusations, but I don’t care anymore.
The point is that only you can see pretty graphics and ambient lighting, everyone else only sees you beating their ass.
