Hello, I'm looking to upgrade an old computer from 2008 whose MOBO I just can't take much further. I want to change the MOBO and processor and keep the rest. Its a mid size case with a 650w PS, 8g of ddr3 ram, 250g HD (will change both of these later) and a Radeon HD 6670. I had bought a new graphics card from a friend only to learn the processor handle it so now I'm looking to resolve that. The card is a MSI HD R7850-2GD5/OC so I'm guessing ill need a board with gddr5 and a PCI-EX 16 slot. I'm right in assuming the ram will work right? I will change it later but am trying to upgrade over time. Also I read that I have to erase my hd because im changing the motherboard, is that true? So do I back up my essentials and just install windows after? If theres anything Im overlooking please let me know.
