Dear Friends, I have a pc with 80 GB SATA hard disk and I would love to buy a new one with 500 GB of space, but the current rates are too high and do not fit my budget. So I have decided to upgrade my system with a new motherboard and 4 GB of DDR 3 RAM. I have a cpu Intel Dual Core 3 GHZ and it is hardly 3 months old. My current motherboard is Biostar G31 M7 TE with only 1 GB of DDR 2 RAM. Based on your experience, can you please help me find a good quality motherboard that can support 4 GB of DDR 3 RAM and my current CPU which is Intel Dual Core 3 GHZ? Please do mention the cost for both 4 GB DDR 3 RAM and new motherboard. My budget for both is a max of 4500 rupees. Thanks.
