Ok, so my plan is to basically have a PC and Xbox 360 linked up to one screen. I don't mind whether this is a PC Monitor or a HDTV (Would prefer HDTV).
I have a fairly large budget for this but I'm not mega rich, or, well even semi-rich at that!
I placed an order previously with E-Buyer for an Antec Sonata 3 Case with a 500w Earthwatts PSU and a Gigabyte GA-EP45-UD3P iP45 Socket 775 7.1 channel audio ATX Motherboard.
For some reason they decided to cancel my order - this might have been a good thing because I found out that for what I need, I'll probably be needing something a little more.. hefty, than a 500w PSU.
If anyone could help that would be great!
