Okay, So Recently I Have Become Extremely Interested In Wanting To Build My Own Gaming PC.
My Brother Used To Build Them And I Used To Watch Him When I Was Younger ..

The Only Purpose This PC Would Have Is To Play Call Of Duty 4 Smoothly Online @ 125FPS On High Quality Settings, Nothing Else.

I've Done A Bit Of Research And Constructed This Price List:

Motherboard: 150.00
ASUS P5Q LGA 775 Intel P45 ATX Intel Motherboard

Processor: 00.00
INTEL Core 2 Duo Processor E8400

RAM: 34.00
8GB Kit (4GBx2), 240-pin DIMM, DDR3 PC3-12800 memory module

Memory: 45.00
SAMSUNG HM500JI Internal 2.5" SATA Hard Drive - 500GB

Power Supply: 0.00
ATX 12V 450 watts power supply (with SATA PIN)

Graphics Card: 100.00
ASUS NVIDIA GTX550 TI PCI-E Graphics Card - 1GB

CD/DVD Drive: 25.00
HP DVD1260i Internal SATA DVD Writer

Case: 0.00
Novatech Galaxy III Case

I Already Have The Case, Power Supply & Monitor ..
The Motherboard & Processor Come As A Bundle @ 150.00
Are These Specs Good Enough To Play CoD4 On High Quality Settings @ 125FPS ?

This Is Really Important So Your Response Will Be Greatly Appreciated <3

If These Do Not Meet The Requirements To Play On High Quality Settings Would Someone Help Me Construct A New List (My Budget Is 400/$615)
