Hey guys, I need some advice on some upgrade paths for my computer. I am planning on upgrading some parts of my computer like my GPU first and hopefully, my CPU next. Although, I am terrified that if I put in just any GPU, it may not work. I have visited this site http://www.pc-specs.com/mobo/ECS/ECS_G41T-R3_(V1.0A)/2814 and has offered me some compatible parts for my PC. But Im not sure if my PSU will be enough to put in a new GPU. Here are my computer specs: OS: Windows 10 Pro 64-bit OS MOTHERBOARD: ECS G41T-R3 PROCESSOR: Pentium (R) Dual-Core CPU E5800 @ 3.20GHz GPU: NVIDIA GeForce GT 220 RAM: 4GB RAM For my power supply, here are some information: SWITCHING POWER SUPPLY - Model: ATX-600W 20+4 PIN. Any help would be great! Thanks guys!
