I want to build a custom desktop PC?

I have 2 laptops and 1 very old desktop.(XP old) I want to make it into a decent gaming computer. Can someone find a vid or make one to help I want to upgrade my graphics card, my Processer and anything else that will make it run as fast and smooth as possible. I currently have a Windows 7 home premium toshiba Satellite L755-S5141. I also have a lenovo thinkpad. I don't know what type it is. My desktop is something.(ill update l8r what the thinkpad is and desktop.) I also wann keep the hdmi… Output? Also I'm working on a very tight budget so all the stuff needs to be under $200 total. I don't want windows 8. Just don't like it.

Added (1). Lenovo® ThinkPad® Edge (0578-A25) Laptop Computer With 14" LED-Backlit Screen & Intel® Core™ i3-350M Processor is the thinkpad

Added (2). and the desk top is a dell dimension 3000.
Also the only reason i'm listing these laptops/ a desktop is because maybe I can use the parts from others like the fan or the power supply and case with the desktop and the vid cards with others. Also i need to know how to wipe a hard drive so I can get all viruses off of the one i wanna use. Then how to install windows to the wiped hard drive.

Does an architect grad student need a desktop computer?

I'm in my second semester of a 3 year M.Arch program. I have a laptop computer - Lenovo Ideapad y510p with 8 gigs of RAM and decent hard drive. I'm a little concerned about the graphics card though. I need it to run programs such as AutoCAD, Revit, Rhino, InDesign etc (usually multiple programs at once) and I'm nervous that my current laptop won't be able to handle the renderings of Rhino. It meets the "system requirements" except for the video card (because I don't know how to compare those)

I'm not 100% sure what graphics card is in my laptop (not sure how to check), but from the lenovo website, my options when buying were:
Select models of the Y510p feature dual NVIDIA® GeForce® GT 755M 2GB graphics with use of Ultrabay.

I highly doubt I paid for the most expensive one… Whichever that is.

I have found a custom built "gaming computer" for sale, but is it necessary for me to get a desktop?
PS: The desktop has a MSI R9 270X HAWK Radeon R9 270X 2GB 256-Bit GDDR5 PCI Express 3.0 HDCP Ready CrossFireX Support Video Card.

Added (1). Specs online state the graphics as: NVIDIA® GeForce® GT755M 2GB

Not sure how that stacks up to OpenGL 2 capable video card

Thanks for the advice! Other architecture grad student's input (or even professionals) on the necessity of a desktop vs laptop only would be appreciated as well!

How to restore my Lenovo computer?

Long story short, A tech support building caught on fire, the computer is in mint condition except with a little bit of smoke smell which is gone now. I completely wiped the harddrive. I used an Acer windows 7 restore disc… It wasn't compatable. It's a Lenovo ThinkCentre intel core Vpro I5, is there any way i can install WINDOWS XP on it instead of WINDOWS 7 and where can i get the restore disc from?

I have a Lenovo H50 desktop and I'm thinking about upgrading my graphics card, I've got a 300 dollar budget?

I also can't tell what my power supply can take or whatever but I found this in a manual.
Some: 180 watts, autosensing, universal (100V-240V)
Some: 180 watts, autosensing, 85% PSU, EnergyStar 6.0, universal (100V-240V)
Some: 280 watts, autosensing, universal (100V-240V)
Some: 280 watts, autosensing, 85% PSU, EnergyStar 6.0, universal (100V-240V)
Not sure what any of this means.

I'm confused in selecting a desktop?

Need some reviews of Dell Inspiron One 20 3043 & Lenovo C260.

What PC Gaming Computer would you recommend?

I've been looking into getting a desktop PC for gaming purposes, and possibly a little bit of media purposes. I would build one, but I don't have much time on my hands and I'd probably screw up while building it, plus I'm lazy. So I'd prefer a retail desktop that I could slightly upgrade in the future. 2 models I've looked into are the Lenovo Erazer x510 and the CyberPower Gamer Infinity 8800. I'm looking into spending no more than $1,500.
