I currently have an HP XW8200 workstation that I use for DCC. It's quite old and has dual xeon processors, 4GB of 400mhz RAM, and an nVidia FX 3400. Would it be better for me to buy a new computer for gaming, or upgrade my workstation? I want something along the lines of a Q6600 processor, and a 1GB 9800GT, I'll probably have to upgrade the 500W power supply and the motherboard too. How much would these upgrades roughly cost?
