Hello! Currently my PC has a Gigabyte GA-EP45-UD3R motherboard, 2GB DDR2 1066 RAM, and an Intel Core2 Quad Q8200. The components subject to replacement are: 450W CoolerMaster PSU, BFG NVIDIA 7800GT. I am planning on adding an additional 2GB DDR2 1066 RAM, a new 530-650W PSU (I need 2 PCIe 6-pin power cables), and probably the Powercolor or Visiontek ATI Radeon 4870 HD. Among this list here: http://www.newegg.ca/Product/Produc...0048 106792627 1067940678&name=Radeon HD 4870 I am just curious on your opinions here, is the video card a good choice with my CPU? (bottlenecking) Also could I have some tips on choosing the right PSU for this build. I want a good quality, stable PSU, for around $60. I am thinking about one these: http://www.newegg.ca/Product/Product.aspx?Item=N82E16817182160 http://www.newegg.ca/Product/Product.aspx?Item=N82E16817182030 http://www.newegg.ca/Product/Product.aspx?Item=N82E16817371015 Finally I am running Windows XP 32-bit (I know I can't use Direct X 10.1; who cares), should I really get 4GB ram? I may do a slight overclock on my CPU because it's stock temperatures are quite low (I know the Q8200 doesnt overclock well tho). Also I have chosen not to get the HD 4890 because I find the extra $40 isn't worth the little bit of FPS. BUDGET: ABOUT $300 CAD. Thanks!!!
