CAN I DO BETTER FOR UNDER 600$? PLEASE READ!!!

For $600, you can do much, much better. But ONLY if you build yourself!
I've never used Cyberpower, but they seem to be a fine company.
You almost NEVER can get a better deal on gaming PC's than one you build yourself. The problem with that build is that they are very light on the GPU, meaning you'd get a bottleneck when gaming.

I suggest you check out the Tom's System builder Marathon $500 PC: http://www.tomshardware.com/reviews/budget-gaming-pc-ph... Throw in an OS and capitalize on falling prices and you have a $600 pc.

Here's a build aimed for gaming(includes Keyboard & mouse no OS though):

CPU & Motherboard: $165-i3-2100 & Biostar H61MH (Great processor & decent motherboard lacks USB 3.0 & SATA 6GB/s)

RAM: $35- Gskill NS (2X2GB)

Power Supply: $45- Corsair Builder Series CX430 (Decent 80 Plus certified power)

Graphic Card: $175- Sapphire Radeon 6870

HDD: $40- Seagate Barracuda 500GB( Same as r0aringdrag0n)

Case: $35- Sentley Black

Optical Drive: $19- LiteOn

Keyboard & Mouse : $32- Logitech EX100(If you need them)

Total (Excluding Rebates) : 546 USD

Rebates: 30 USD

Here's a review of Radeon 6870.
Possible upgrades include :
CPU: $190-i5-2400 (Great Quad Core Processor)
Motherboard: something that supports USB 3.0 and Sata 6gb/s like Asrock H61 worth $75

If you want both upgrades and want to save some money, possible option include :
1. Downgrade HIS 6850 worth $160. Save $15
2. Downgrade the case to Xigmatek Asguard worth $30.save $5

Get this combo :
$250-i5-2400 & Biostar H61MUS3 (lacks only sata6gb/s)
$256-i5-2400 & Biostar (has both the features)
That should be enough.
