$850 gaming system

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:

case
Antec three hundred - 54.95
http://www.newegg.com/Product/Product.aspx?Item=N82E16811129042

hard drive
Western Digital Caviar Black 500GB - 69.99
http://www.newegg.com/Product/Product.aspx?Item=N82E16822136320

memory
G.SKILL PI Black 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) - 49.99
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231209

motherboard

ASUS M4A78T-E AM3 DDR3 AMD 790GX ATX AMD Motherboard - 139.99
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131366

CPU
AMD Phenom II X3 720 2.8GHz Socket AM3 95W Triple-Core Black Processor Model - 134.99
http://www.newegg.com/Product/Product.aspx?Item=N82E16819103649

PSU & video card
PC Power & Cooling 860W and SAPPHIRE 100259L Radeon HD 4870 512MB - 394.98
http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.182373

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.

  1. What resolution is your monitor? and what games will you play?
  2. The build looks good to me.
    I don't know if you're tied to Newegg or not, but shop around and you may save a few bucks. These folks have some interesting combos.

    Good luck on your build
  3. crossfire is overkill for that resolution.

    only time you use cf or SLI is when you have a 1920x1200 or above resolution screen.
  4. www.bbb.com gave ewiz a F-rating
    other wise, id get http://www.ewiz.com/detail.php?name=EV-G260_55&src=DC&sid=u0t0f0fp19877c0s1056 and theres a 10$ coupon. so total is $140
  5. yes but most retailer reviewing sites have user reviews at over 8/10 average.
  6. does anyone know of any other computer part retailers so i can avoid this 7.46% tax from newegg?
  7. 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
    http://www.newegg.com/Product/Product.aspx?Item=N82E16813128384 $128.99

    or

    GIGABYTE GA-MA790X-UD4P AM3/AM2+/AM2 AMD 790X ATX AMD Motherboard - Retail
    http://www.newegg.com/Product/Product.aspx?Item=N82E16813128387 $109.99

    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
    http://www.newegg.com/Product/Product.aspx?Item=N82E16820231246 $59.99

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

    Western Digital Caviar Black WD6401AALS 640GB 7200 RPM 32MB Cache SATA 3.0Gb/s Hard Drive - OEM
    http://www.newegg.com/Product/Product.aspx?Item=N82E16822136319&Tpk=wd6401aals $74.99
