Hello! I'm posting this to make sure I'm going to buy something that's going to work with my computer. Here's (hopefully) all the information you'll need to help me make a good choice. Thanks!! I play WoW mostly because that's the only thing I can play on my computer. I am very interested in FPS games (Bioshock makes me slobber on my keyboard) F.E.A.R. and Portal look very interesting too and everything else in that area. I'm willing to spend a decent ammount of money (200$~ish) so that I can have a good gamming experience. You know, high frame rate with beautiful graphics. Here's some information about my power supply that I could pull off the side. HIPRO (The brand name or company, it's in big letters at the top) Model: HP-D3057F3R AC input : (47-63 Hz) 100-127V/8A 200-240V/4A DC output: +12V = / 19A +12V shall not exceed 268W Max output power 300W Now here's some of my computer specs. I used the program CPU-Z to get them. (Giving information highlighted in the guide on the forums I saw) Name: AMD Athlon 64 X2 3800+ Core Speed: 2004.2MHz I couldn't see the second picture for some reason in the guide, so here's what I think is useful from "Mainboard" Model: NODUSM3 Chipset: NVIDIA GeForce 6150 (lol I know right?) Southbridge: NVIDIA nForce 410/430 MCP (In the BIOS section) Brand: Phoenix Technologies, LTD Version: 3.07 Date: 08/02/2006 Memory (I'm planning on buying an extra 1GB) Type: DDR2 Channels # : Dual Size: 1024 Mbytes Also, I'm from Canada. The guide told me say that O.o This is the information I thought was useful. If you need anything more to know what would be best, please let me know.
