Building a desktop. My mid 2009 mac book pro doesn't cut it. Neither does my current windows PC machine. What PC desktop components I have extra to use if I wanted too are the following: GPU - Nvidia GTX550 Ti 500w SPU Case Random HDDS Monitors Etc What processor should i use? And also suggest a Mobo. Gaming isn't a concern. I'll use this for video editing and daily. I also have a possibly good Intel i5 2500k that still should be functional from my son's old rig. Just no mobo (which we believe to be fried. Really just looking for an economical mobo/CPU Combo. Mostly editing video and photos from my P2V+ Thanks for any help you can provide. Not looking to break the bank.
