If u upgrade, make sure your board supports SLI, because u can jumper 2 video cards together. Dual core for sure. Gigabyte LAN if u do LAN parties. Make sure your video card has native RAM built in. Some cards steal half their RAM from your motherboard. 450 to 500 Watt power supply. 350W won't cut it. Lots of cooling fans. Spend your money on the greasy parts. Stay away from lights, fish tanks, glow in the dark, etc.
