I currently play WoW on a year and a half old HP laptop. My guild is raiding heroic ICC 25, and during combat (boss fights only), my FPS drops to around 5 with all settings as low as possible, and I frequently get disconnected. 10 man it's around 15 FPS. Being a healer, it's incredibly frustrating. Looking to get a desktop for around $2k that gets decent FPS in combat, but have no idea what's good and what's not...any suggestions?
