I built a budget system for myself this last summer and it was a lot of fun collecting parts, trying to get the best deals, checking prices, etc. Well, the system is finished and upgraded a couple times since (more ram, new cdrw, more fans) but I really haven't had much more to work on. The processor won't go past 850 and the video card doesn't overclock very well. I did the Via tweaks to improve memory performance and this last weekend, I found that I could run my two chips of RAM at 222/5 and 232/5. With DDR coming out, that isn't very exciting either. I play games, look at frame rates, blah blah blah, but most of the fun is in building the system. Now I'm planning a second system only half a year later. I was wondering what you guys do after your system is done and tweaked?
