I have hp 4320s laptop. I do upgrade my system. What motherboard supports CPU? I will work properly following processors: Core i7-840 meters, running a 45w, Core i7-920XM-works 55w, Core i7-940XM-works 55w. These are Socket G1 (rPGA988A). 4320s laptop has Intel chipset HM57.Teoritichno he should maintain the above processors. What is your opinion? Will i5-460m, to be replaced with I7-940 meters or i7-840m?
