Its been awhile since I upgraded anything in my system. Here they are! Swapped the Athlon 7750 BE for a Phenom II 940 BE Swapped Antec Basiq 500 watt PSU for Antec Earthwatts 650 Swapped Stock CPU Heat Sink Fan for Corsair H50 Water Cooler Swapped Server 2008 64bit for Vista Ultimate 64bit, soon to be 7. All inside an Antec 900 I have the 940 clocked @ 3.3 but I start having issues at 3.6 Temps OC are 29c Idle 33c Load CPU System Temp 30c Idle 35c Load HD 4850 60c Idle 75c Load Thinking about picking up another 4850 for crossfire, they seem to scale well. Any input will be great!
