I have an: DIXONH55ITX Socket 1156 Advent Firefly FP 3104 System Motherboard I'm looking to upgrade for 2 main reasons. 1.) Upgrade my Ram, (as the limit of ram for this motherboard is 4gb.) 2.) More than 1 PCI-E slot. (There's only one on this motherboard.) But my main question is: What do I need to take into account when upgrading my Motherboard? (Compatibility issues etc.) Also any motherboard recommendations (under £200). As I'm planning on upgrading my computer to a gaming rig. Any replies would be greatly appreciated.
