Personally, I would switch out the sandy bridge e, and replace it with a 3770k or 3570k and use the extra money on a 660ti! Just preference though. To be honest, you're not going to see a real difference at all between your current chip and ivy bridge. In some cases, it may actually be better.
Also, I don't know what your future plans are, but it wouldn't hurt to purchase a slightly higher wattage PSU in case you decide to crossfire later on? Possibly in the range of 600-750W. No harm in having leftover power!
So I ordered and received all this stuff. And started putting it together today. Once I had the mother board in the case and the memory and CPU and power supplie hooked up I figured I would make sure the bios screen would come up. Turned it on and the CPU fan went on but nothing on the monitor. I have not connected the DVD or hdd yet. But I thought I should be able to see some sort of life.
Any I wrong? Should I continue and connect the DVD and hdd. Suggestions?
