My Win7/64U machine runs like a champ 24 hours a day 7 days a week and have no issues. It is the Intel i5-760 overclocked to 3.8Ghz, Asus Z68 Board, 12gig of 1833 DDR3 RAM, 1Gig nVidia Video Card, 2 SATA3 1TB drives, 2 1.5TB External Drives, 7-120mm fans, CoolerMaster HeatSink with 2-120mm fans in Push/Pull configuration. On my previous workhorse cooling was the main issue and made everything run like crap even with XPPro-SP3 but since I built this one 18 months ago its been great. I am fixing to build a Intel i7 3rd gen system with 32gig of 2133 RAM and 2 SSD in Raid 0 and put the old one in theater room
