I'm thinking about upgrading my mob which is currently a old dell Dell Inc. 0FM586 (Socket 775) atm..I want to stick with my processor (Q6700) since its decent but would like to upgrade my mob with something that is compatible with it...ddr2 ram is expensive and would like to find one that is possibly ddr3...is there one out there, if so which would be best to get... that is within range of 100$ ?
