Alright, I'm looking to build a new gaming rig, I've got the OS, harddrive, monitor, and case. I'm looking at the 2500k, a gigabyte z68 board, and some G.skill 1600 ram. But I'm unsure of what video card to look for and a PSU. Any suggestions? I was looking to spend around 700 in total, with the parts I've already looked at there's around 200 for the video card and 70 for the PSU.
