Antec 1000watts? Talk about an overkill! Good PSU tho.
About the motherboard get one with a Z68 chipset if you can afford it. If not get a P67 nothing less.
Ah that PSU was a goof on my part - forgot to put things on different rails - had specked out a 750 as being ample with some reserve then ran into power problems not thinking about putting differnt things on different rails - so yeah.... Over kill city.. As to the motherboard I see this one as a popular choice
ASUS P8Z68-V PRO/GEN3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS - I am looking at ASUS products as that P5 althought overkill, perfromed well for me , although If thsomeing in the same price range is better then I'd go that way
