Hi, I know you guys probably hate these kind of threads but I really need help building a pc. This will be my first time building a pc, I am a console gamer, but Dolphin intrigued me, I find it awesome that I can play my Wii games on my pc in 1080p (possibly). So I have done some research on this and came up with these parts. Now I didn't include a case and an disc drive because I figure I can get any cheap thing, but maybe down the road I would like to get a blu ray disc drive and burner, but I am getting off track. For the CPU I chose the AMD Phenom II X4 955 Black 3.2GHz Quad-Core Processor because I heard great things about it online, and I figure it can run Dolphin pretty well. For the video card I chose the HIS Radeon HD 7870 2GB Video Card because I heard that you can easily oc it. Now none of this is definite, I was think of spending a little more money to buy a Radeon HD 7950 or a GeForce GTX 660 Ti, now I don't really know which one is better, I have read many articles on both, I have heard that the 7950 can be oc easily, but the 660 Ti is a better deal. But is it even possible to just "throw in" one of these graphics card with the rest of the pc's parts? So many questions
So what do you guys think? What can I improve on? Feel free to say whatever you want to say, I really need the help. You can rip this apart, or you can even build me a totally new one from scratch. I really don't mind, I just need the help.My budget is around $650 dollars and I would like to be able to run games on dolphin in 1080p. I really hope I am not coming off as an annoying "newbie." Thank you for all of your help.
Here are the specs of my first idea:
