Hello guys I'm planning on buying a new (gaming) computer. I was thinking of a quad core, but is that necesarry? Also which motherboards do you recommend for use with a quad core? I think I will go for a geforce 8 series but don't know yet which one and with how much memory. DVD-Burner and HD aren't necesary since I already got some nice ones here(Optiarc Ad-7173A and Seagate 500G Serial-ATA II) I'm willing to spend about 400-650 euro's. So any suggestions?
