that a 8400 gs? i currently have that setup 4gb ddr, and a 512mb 8400gs with an athlon 64 X2 6400+, the cpu is good, but its the gpu that holds it back, it barely plays wow on low 1080p, i have a similar setup with again 4gb ddr2 with a am3 athlon II x2 240 which for its lower clock speed is similar to the 240, paired with a geforce 210 plays wow on medium alot better. So a core 2 duo/quad, or athlon/phenom am2/am2+ dual/quad core will be fine
