As I can't use links I've used the ebuyerDOTcom quickfind codes I'm planning to upgrade to Windows 7 Professional, from Vista Windows 7 Ultimate (Not literally upgrade, I know I couldn't do that from Ultimate to Professinoal) and a Radeon HD 5770 from a NVIDIA GeForce 9600 GT sometime soon and I was wondering if there was anything else I should consider to update while I'm at it. If they don't really need to be updated and should be fine left how they are I'll leave it. Its just that I read the PSU is rubbish and I think the CPU is 4/5 years old now? So thought it might be time to upgrade. Motherboard - Asus M2N-E SLI PSU - EZCool ATX-650JSP 650 Watt CPU - AMD Athlon 64 x2 My main concern is the PSU, would something like this 141006 be a good replacement? Wasn't sure with the Motherboard and CPU. If it would fit would 186428 be a good replacement for my CPU? PC is used for general use, Gaming, Photoshop. I'd like to try things like Streaming and using Valves Hammer Editor and other things like it so if it could handle tthose it would be nice. As a for a budget, around the same price as the items I linked. Cheers.
