Need help with a computer upgrade

[Rhunyor]

Hello, everyone. I was hoping to get some help with an upgrade I'm thinking about doing with my PC. I'm pretty much a novice when it comes to such things and have gotten a lot of help from friends in the past, so I apologize if I do not understand tech terms as well as others. Anyway, I'm aiming to get my PC on par for the games coming out these days (specifically PS2) and any help any of you can give me would be much appreciated.

1. Are you building this computer yourself or having one built for you (Like HP, Alienware, or even a small shop)?

I'm building the computer for myself

2. What is your budget and does that include shipping/taxes?

I am trying to stay under $400

3. Where do you live (Please list town, state, and country)?

My current residence is Ohio in the U.S.

4. What do you need this computer to do (like gaming, Photoshop, and so on)?

Gaming

5. What parts will you need for the computer? List what parts specifically, saying you need everything will not do.

Power supply, RAM, maybe a new Motherboard/CPU if I can afford it/ it is necessary

6. Are you reusing any parts for this computer? If so say what parts (make and model).

This is what I am running on at the moment. http://www.newegg.com/Product/Produc...82E16883107657 I have upgraded the video card to a Nvidia GeForce GTX 260 and it has a new case (http://www.newegg.com/Product/Produc...82E16811119216) I am also reusing my hard drive

7. What kind of monitor/resolution do you have or want to get to use for the computer?

8. Do you have already have a OS or do you need one? What OS is that?

I am running on Windows Vista 64bit Home edition

9. What are you looking for the motherboard to have feature wise? Like SLI, Crossfire, Firewire, USB 3.0, Sata 6.0 Gb/s, and so on.

I honestly have no idea. I simply want the new components to work with the reused ones and not bottleneck.

10. Any plans to overclock the CPU or GPU?

No.

11. What time kind of time frame are you planning on ordering these parts?
Hopefully soon. Perhaps within the next week or 2.

Thanks again for any help you all can give me. Let me know if you need any more information to assist you with my upgrade
