$700 AMD 785 Mobo Gaming Build- which CPU/Mobo/VGU/Ram works best?

PURCHASE DATE: In the next 7-10 days

BUDGET RANGE: US$700 minus $175 (already spent for the case, HD, and PSU) = $525 left to spend on mobo/cpu/ram/vgu/dvd/etc.

SYSTEM USAGE: For gaming (SIMS 3, Civilization, Flight Simulator X), Photoshop CS4, Access and Excel.

PARTS NOT REQUIRED: keyboard, mouse, monitor, speakers, 17" LCD monitor 1280 x 1024, OS XP PRO, Can use Win 7 Beta.

Already have a Antec 300 Illusion R Case http://www.newegg.com/Product/Product.aspx?Item=N82E16811129066 , a Western Digital "Black" 750 Gig Hard Drive http://www.newegg.com/Product/Product.aspx?Item=N82E16822136283 , and a HEC Compucase 585 Watt power Supply http://www.newegg.com/Product/Product.aspx?Item=N82E16817339012 .

PREFERRED WEBSITE(S) FOR PARTS: newegg.com, zipzoomfly.com

PARTS PREFERENCES: AMD Phenom II CPU (I like the 720BE, 550BE, and 945 (95w or 125w, don't know if they can fit into the equation but I like them)& 785 mobo's with sideport memory (from what I have read, I like the Asus ASUS M4A785TD-V EVO AM3 AMD 785G, the GIGABYTE GA-MA785GPMT-UD2H AM3 AMD 785G, and the MSI 785GM-E65 AM3 AMD 785G HDMI Micro ATX. These 3 mobo's are $90-$100 and there are good combo deals on zipzoomfly.com with the CPU's.

Want 4 GB Ram, open to suggestions on what speed to get, the boards support 1333 to 1600 to 1800 OC'd.

Open to either ATI or Nvidia VGU.


MONITOR RESOLUTION: (1280x1024 for now, will be getting either a 24" 1920x1080 or 26" 1920x1200.

ADDITIONAL COMMENTS: My goal is to balance the critical components (CPU, Mobo, Ram, and VGU) for the money remaining ($495 after buying a DVD drive). Realistically, given the type of gaming the system is expected to do, I am certainly not expecting to make as proportionately big an investment in a VGU as most gamers would. By the way, the Antec Illusion case has 4 fans (top, front, side, and rear) so I am not sure if I will need a CPU cooler.

If you have any experiences or recommendations, relating with the components, I would appreciate any and all input.

Thank you.

  1. As an alternative mb have a look at the GIGABYTE GA-MA770T-UD3P AM3 . Its only $85 , the performance will be the same as a 785 board , but it doesnt have onboard gfx .

    AMD Phenom II X4 945 Deneb 3.0GHz + SAPPHIRE Vapor-X 100269VXLE Radeon HD 4890 1GB combo
    $335 [ after MIR]


    Patriot Viper 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 $85

    Total is $505

    Outside the budget , but includes a high end quadcore and a 4890
  2. For FSX get a quad for sure... BE makes overclocking easy on any board.

    You don't need onboad graphics unless the board you choose happens to have it.
  3. First thing you need to do is return that PSU. No offense, but that one is junk. I'll put together a list including returning that PSU, and see if I can get you in budet.
  4. For a 4890 I would suggest a 650tx all the way.
  5. Ok, so assuming you can return that PSU, that gives you $525.

  6. Thanks for the feed back so far. One of the reasons I was looking at the 785 boards was because of the onboard video capability with sideport memory. The sideport memory was a plus from what I have read and with the onboard video, I was contemplating delaying the VGU purchase for a month or two to take advantage of possible price drops.

    Irregardless, I am a fan of the 945. I do have question, what is the advantage of the 95W over the 125w version?

    Also, Newegg has a 24 hour special on this PSU: A-Top ATP-AP700SC 700W ATX12V2.2/EPS12V SLI Ready CrossFire Ready Power Supply for $29.99 after 60.00 MIR http://www.newegg.com/Product/ProductReview.aspx?Item=N82E16817184009

    I do like the choice of the ram and the the the VGU's although I think the 4890 is probably more card than the budget would allow for. The Gigabyte MA770T-UD3P is a board I had never considered and it is interesting that 2 veteran posters have recommended it. It would certainly work and is priced right.
  7. Two things to look for when buying a PSU. Active PFC and 80+ certified. That PSU has neither. If a PSU fails, it has a good chance of taking other components with it. You do NOT want to skimp on the PSU.

    If you prefer the 785G, go for it. Just be sure you get one that's DDR3 to match with the RAM. I'm not sure I expect big price drops. AMD GPU prices have been declining slowly as we've neared the new 5xxx release. I'd imagine those cards will come at a premium for a while, keeping the current prices for existing cards at or near their current price levels.
  8. Getting a

    MOBO:785G ASUS + RAM: DDR3 1333 OCZ combo
    GPU: XFX 4890 + CPU: x4 945 Combo
    PSU: 650tx
    OPTICAL: LG 22x

    will equal out to be $685.
  9. Definitely got the message on the PSU Mr. AMD T, thank you and I will do so. Please share your thoughts also regarding the pros and cons of the 95 w and 125w versions of the 945. Fullmetall, my total budget was $700 minus $175 already spent on the case, HD, and PSU (which I am returning), so I have $550 to spend, not $700... thanks.
  10. I know that, I was giving you the price of what it would cost to get a 785g mobo and a 4890. Seeing how you dont have the monitor you need for that card just yet, the $100 dollar 4850 could drop you down close to that price.
  11. Cool, so 95w or 125w 945 CPU?
  12. The lower wattage CPU would be the one to go with.
  13. Because it will use less power, run cooler, be compatible with more motherboards, and have more overclocking headroom.
  14. Good thinking with the 785 and delaying the gfx card . Ive done the same sort of thing a couple of times and it makes sense .

    Since you are going to upgrade monitor theres no point buying a midrange 4850 , so I still think the 945 + Patriot memory and sub out the 770 mb for a quality 785 . Preferably Asus or gigabyte

    The PSU you have isnt the best , but it should work

    definitely the 95 watt 945
  15. Thank you sir.

    Just to be sure, are you you saying you like the Asus Evo and the Gigabyte 785GPMT-UD2H that I mentioned originally? FWIW, of those two; I favor the Asus Evo (both are around $100). However, Zipzoomfly.com has a MSI / 945 combo for $240 with free shipping or just the MSI board for $80 w/ free shipping (no MIR's on any either!).

    Seems like NewEgg has been very stingy (or is just me?) on their deals lately. I have seen very good reviews on the MSI on 3 sites. Thank you again.
  16. Yea well you can also get the Asus 790gx + the x4 945 combo as well on newegg for $254. Doesn't sound stingy to me. But, all'n'all the only way I see you getting the 4890 to match up with the monitor your wanting to get is Outlander's build.

    OK IS IT MY VIDEOCARD PROBABLY NOT I TRY ONE MSI 4870 1 gig and my test result with 3D MARK VANATAGE is 10,000 +-

    Is it because I'm with Vista 64bits?

    Or somethink in the bios (patch 2)?

    Please I need your help...
  18. Well first, why 2x 2x1 on the sticks and not 2x2. Chances are of 1 failing you having to buy 1 of 1/4th of whats there and hoping it will work. Second, Seagate 750gb.. Seagates arent bad but, if I remember the 7200.12's were out at this time in stock. PSU, x-finity, never even heard of x-finity. Best to stick with a brand with good productivity. Vista Ultimate is definitely not worth the money..

    2nd build, don't know when it was bought so, im not going to tell you the skimps in it. If you think your 4890 isn't performing well, put it in the 2nd build and take out the 8800's..

    By the way, if your going to post, make sure you make your own thread so people wont ignore you when posting in someone else's thread.
  19. Thanks for the advise... :heink:
