I have an old system with old hardware. I am going to start building a gaming rig(I sold my old one for bills and am now financially more stable, but still on a budget). I plan to just upgrade about half of the components once in this system, and then in about 2-4 weeks I would upgrade the rest most likely in a new smaller more vented case. I definitely need a new mouse and keyboard and think I found one. I currently have a 250W PSU with a Dual Core 3.5GHz processor(Phenom x2) which is very old and slow. It can run some games on minimum settings but not many. And they still only get 40-60 fps on minimum settings 720p. I am trying to decide if I should go ahead and get the R9 270 and a 500W PSU(bronze certified) with the mouse and keyboard(my mouse is HORRIBLE and makes my hand cramp), or start with a new mini-ATX motherboard and an FX-8350 cpu. I have 4GB of ram so I think I'm leaving that for last and of course the case will be last because the one I have is fairly decent. I also have a 7200rpm 1TB HDD so I think I'll keep that too. Monitor and speakers are also covered. I just really can't decide between PSU and GPU or CPU and MOBO. Would I need a PSU stronger than 250W if I got the FX-8350 or would the 250W work fine? Thanks for your help guys. If you have any other suggestions or just want to flat out tell me I'm wrong feel free to haha still learning. This is only my third PC and the other ones I had the money to put decent parts in all at once.
