I currently own a 5 year old 1U server that's aging and its a miracle there hasnt been any hardware failure. It's specs are: 2x Intel Xeon 5050 (Dual Core and its using crappy P4 architecture) 4 GB Ram 10,000 RPM WD Velociraptor Hard Drive I'm getting a replacement server built later in the week and I want it to be able to handle as many concurrent connections as possible. Server will be running just 1 site (xenforo) and a few smaller sites on Ubuntu Server Edition (all on the same domain). How much ram should i get? 8GB? 16GB? Keep in mind the box will also be hosting the MySQL server. What about CPU? Is a single CPU with Quad-Core better or worse than 2 CPU's with less than 4 cores each? What about CPU type? Xeon's are expensive, but aren't the desktop CPU's catching up in performance (eg. Intel Core I7's)? I'll probably get a single SSD hard drive and im not too worried about hardware failure as i keep local backups of everything. Thanks in advance.
