I'm looking for a system on the budget to replace one of my units for WotLK. My main and one of my secondaries will handle Wrath just fine, but I'm worried my other secondary might struggle, as it's just barely keeping up as it is. I want to get a new system that can replace it, but I want to keep it on a budget, as I am throwing down 200+ for 5 copies of the xpac as well. I run two copies on the system, with the resolution set to 800x600, and the windows split horizontally. My current system is a 3ghz p4 with the hyperthreading gimmick. It has AGP and ddr400, so it is starting to show its age. Any suggestions?
