Thanks in advance for your input and advice. I have a mini-tower computer with an ECS H61H6-MV Micro ATX Motherboard. I want to upgrade my video card to an ASUS Radeon HD 6450 and would like to keep my current computer case. I am not a gamer, but looking for a bit more power to run Sony Movie Studio and render videos a bit quicker. My current set up includes Intel CPU G620 @ 2.60GHz, 8 MB DDR3 RAM, ATI Radeon HD 5400 series video card, and a 2 TB Hard Drive. I plan to upgrade the processor to an Intel G3258 3.2 GHz, the power with a Corsair CX500M, and the RAM to 16MB. Any thoughts on successes you've had with Micro ATX motherboards?
