I wish you the best of luck in building a new computer. I have kept my computer for about six years, too, and it is definitely starting to show its age. I am last to load in any game that I play with a public loading screen. It's embarrassing! This thread caught my attention only because it sounds like we are in similar situations.

What are you going to be using your computer for, primarily? What is your budget? I will show you what I plan to build later this year: Intel i7-2700K, ECS GeForce GTX 560 Ti, Antec Three Hundred Illusion - System Build - PCPartPicker
