Windows 7: Upgrade a System - Build a New System

I have several things going on here. I have a HP dv7 latop I have to replace the fan on it. I also have a family member that has 2 old desktop systems that they no longer use, (one works the other I think needs a power supply) so I want to upgrade one of them if you think it's possible for my needs. Not sure if you call it gaming but I run Microsoft Flight Simulator X, the new Microsoft Flight, and Train Simulator 2012, and I am looking at DCS Warthhog 10, (which is about 6 months to a year old) at this time. But it is mainly just for getting FSX to run at decent frames per second, and such. Can you tell I like simulation software! FSX as it is known came out in 2006 but is very graphics and processor intensive and generates alot of heat. Since it basicly broke the fan in my laptop, thus the need to replace the fan. I want to upgrade one of the old desktops from several years ago with a graphics card, memory, and possibly a new power supply. But I want these parts to be able to be moved over to a completely NEW build when I am ready probably early 2013.

I will have to get the model numbers and info for you on the old desktops for you to be able to tell me if this is possible. I do know that are running Windows Vista, 32 bit I am sure. And they probably don't have a dedicated graphics cards!


Does this make sense to you?

We're going to need the full specs of the desktop to be able to help in any way. We can't point you in any direction without the correct information.

You only want to upgrade a maximum of 3 parts now (graphics, memory, PSU) and you want to be able to use all of those parts in a new build in 2013?

That shouldn't be a problem for the power supply, but any new memory or graphics card you put in the old PC may or may not be transferable to a new build in 2013---it depends on what motherboard and CPU you now have in the old PC.

More details needed.

Looks like I will have to work on a new system as the old desktops are too old. One of the model number is Gateway G5465E! The specs are way too low for what I need. My dv7-1444us laptop is better than those are. I'll post some system builds later.
