I need to upgrade my computer and I want to know what I need?

[tankburger]

Here are my specs from speccy:

Operating System
Windows 7 Home Premium 64-bit SP1
CPU
AMD Athlon II X4 645 39 °C
Propus 45nm Technology
RAM
6.00GB Dual-Channel DDR3 @ 666MHz (9-9-9-24)
Motherboard
Dell Inc. 04GJJT (CPU 1) 53 °C
Graphics
Generic Monitor (1920x1080@59Hz)
ATI Radeon HD 4200 (Dell)
Storage
698GB Western Digital WDC WD7501AAES-75W7A0 ATA Device (SATA) 43 °C
Optical Drives
PLDS DVD+-RW DH-16ABS ATA Device
Audio
AMD High Definition Audio Device

My PSU is retail brand with only 300W

I want to be able to run 3 monitors and play games like skyrim comfortably. I know I need a knew power supply, will that require me to get a new motherboard? Should I replace my CPU? If I get a new motherboard and power supply will I be able to keep my hard drive? Also, I will be upgrading my graphics card. My budget is $600. What should I get?

http://pcpartpicker.com/p/Tc8hXL you should also get new RAM when you have the budget.... You can reuse hard-drive and everything not on this list... It should run 3 monitors, it may not be "comfortably" 100% of the time.

You seem to have the Dell Inspiron 570 computer.... am I right ?

It is, I know, look at my signature.

Also, add to the new build new OS, Dell OS is OEM and would not work on new build.

Or you can make your 570 like mine, just with newer GPU, but there can be problem due to UEFI, I doubt that Inspiron of that age will support it.

Can you tell me what kind of case you have there ?

I have a Dell Inc. model D06M. I will most likely need a new case, can just barely fit the PSU now

At best, after upgrades, your case might look like mine (before I upgraded the case)

Those are original cases, note that not all of them have removable panel opening, so it is solid metal, like mine was

And this is how, approximately, it looks now

Messy, but not bad for cooling overclocked Phenom II x4 965 BE @ 4 GHz. It survived Intelburn and Prime95 for hours and hours in worst settings. Was able to play Battlefield 4 at High at 70 fps (I have IPS monitor, so fps are monitor limited).
