$850 gaming system


Apr 12, 2009
Hi, this is my first build, and i want to make sure everything is compatible and that i am getting back best bang out of the system. i plan i getting the system by the end of the month and its primary function is gaming and i plan on spending $850-ish. i will do some video editing and photoshop, but that is not necessary.

the place a plan to buy these parts from is Newegg.com

I will not be needing a Monitor, mouse, keyboard, speakers, cd burner or an operating system, as i already have those.

Here is the build i came up with:

Antec three hundred - 54.95

hard drive
Western Digital Caviar Black 500GB - 69.99

G.SKILL PI Black 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) - 49.99


ASUS M4A78T-E AM3 DDR3 AMD 790GX ATX AMD Motherboard - 139.99

AMD Phenom II X3 720 2.8GHz Socket AM3 95W Triple-Core Black Processor Model - 134.99

PSU & video card
PC Power & Cooling 860W and SAPPHIRE 100259L Radeon HD 4870 512MB - 394.98

Total - 844.89
After rebates - 809.89
with shipping - 878.62
with shipping + rebates - 843.62

I will probably upgrade by crossfiring an additional 4870. will my PSU handle it? and are there any suggestions to my build?
I will also be adding in after market cooler in the future. although i will be gaming, i do not plan on overclocking, as i want to increase the lifespan of my machine. I will also add thermal paste later.
the only concern i can see so far is the motherboard

I will play at 1680x1050 res.
I mostly play RTS games - A lot of Red Alert 3 currently, planning to play Starcraft 2 when it comes out. I also play FPS games, but not very much - Call of Duty 4, Crysis. MMORPG's are also fun to me, but i get bored of them really fast.

EDIT: i forgot to mention that i live in new jersery, and that there is a $60 tax on $850. If you could offer a website with a great selection of computer parts, it would be appreciated.
I've had good luck with www.zipzoomfly.com. No one has mentioned a compatibility problem with the original build. You picked DDR2 RAM, but the motherboard requires DDR3 RAM. I would get one of these motherboards instead:

GIGABYTE GA-MA790GP-UD4H AM2+/AM2 AMD 790GX HDMI ATX AMD Motherboard - Retail

GIGABYTE GA-MA790X-UD4P AM3/AM2+/AM2 AMD 790X ATX AMD Motherboard - Retail

AMD CPU's actually perform better with DDR2 1066 RAM. I really like the PI Black RAM, but I would get DDR2 1066 to maximize your performance.

G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory - Retail

The 640GB drives are faster than the 500GB models and don't cost much more.
