Hi guys, glad to join these forums. So I'm going to build a better system for myself and I need some advice and ideas from you gurus. Here's my current system (I only mention the components I will be buying/upgrading): AMD X2 5600+ ASUS M2N-SLI Deluxe 2x2GB Kingston HyperX DDR2-800 ASUS EAH4850 (bought that a week ago as my Radeon X1950 XT was overheating BADLY) Gigabyte 180 case ( http://www.techpowerup.com/reviews/Gigabyte/Triton_180 ) I'm thinking of getting the following: AMD Phenom II X3 720 Motherboard - no idea, see questions 2x2GB RAM - got questions too Corsair TX 650W Case - ? I'm aiming for a mid-range value gaming PC with a little bit of overlocking. Ok here are my questions: 1) What RAM should I get? Is there any difference between DDR2 1066 and DDR3 1066? How about DDR3 1066 and DDR3 1333(is the difference worth the $)? (please take that CPU into account) 2) What motherboard should I get? (I don't need any fancy features, just stability and low price) 3) I'm currenly using that Gigabyte Triton 180 case and it has 2 12cm fans (rear and front) which is decent airflow I guess. In practice, how much lower would the CPU/GPU temps be in an average quality case with 3-4 fans? I'm not sure if I want a louder case or higher CPU/GPU temps. Thanks in advance guys.
