What kind of issues are you having with Winderz? Not to be off-putting, but a lot of folks have issues with Winderz that are pretty easy to resolve. Aside from that, there are several flavors of Linux, each with their own benefits and problems, plus the learning curve. Linux also has many benefits, but there are downsides such as gaming (limited), and the integration of some programs is fairly spartan. Also there are some hardware compatibility issues (think AMD graphics drivers). I'd suggest that you look into both solving your Winderz issues and set up a dual boot for a Linux distro and play around with one in order to get a feel for what is available and compare to your computing needs.
