I ordered a new monitor from Newegg.com on Monday, and it just arrived today! I'm on it right now, and I have to say, I absolutely love it!
I used to have a 19" CRT Envision monitor. Now I have a 19" SCEPTRE X9 G-Naga IV LCD monitor. Although they're both 19", this one seems to be bigger. It can also support better resolutions, and I'm now running at 1280x1024 instead of 1024x768. It's a big difference in games.
The image is crystal clear, and with the 8ms response time and 75Hz refresh rate, there's no "ghosting" or "trailing" effects like some LCD monitors do. (PSP for example)
If you're thinking of getting a new LCD monitor, I definitely recommend SCEPTRE. I'm very impressed with this monitor, and it's my first ever LCD.
I also got a new speaker system a few weeks ago. They're Altec Lansing VS2221 speakers with 2 satellites and 1 subwoofer. It produces awesome sound, and even has an added feature where you press the SFX button and it produces a wide range surround sound, with only 2 speakers!
The past month has seen some great upgrades for my computer. Now nothing for my PC is more than 1 year old. 8)
