$750 Buget System - Thoughts on Setup?

APPROXIMATE PURCHASE DATE: End of year
BUDGET RANGE: $750 - 800

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming, Watching Movies

PARTS NOT REQUIRED: Keyboard/Mouse, HD (640 GB WD Blue)

PREFERRED WEBSITE(S) FOR PARTS: NO Preference
COUNTRY OF ORIGIN: Philly USA

Current Shopping List

AMD Phenom II X3 720 BE (Newegg $120)
GIGABYTE GA-MA790X-UD4P (Newegg $110) - no preference here, saw good reviews, if you can recommend better i'm all ears
XFX Radeon HD 4870 (CC $120)
OCZ Reaper HPC 4GB (2 x 2GB) DDR2 1066 (PC2 8500) (Newegg $71) - no preference - cheapest that works with the mobo
Enermax Infiniti 720W - $45 (after rebate)
Case - Any recommendation for a cheap case
ST2410 24” Full HD Widescreen Monitor (Dell 200)

Main concern is that the Enermax only has 2x6 PCIE and 1x6+2 PCIE. I plan on upgrading to crossfire in the future (2+3 years - to semi future proof my computer). That will require 4x6 PCIE, so do I need a PSU with 4x6 PCIE or can I just use a molex to 6 PCIE adaptor on the Enermax?

Also overclocking AMD to 3.4-6 GHZ

Thanks all for the feedback

  1. Second the AM3/DDR3.

    Also, do not get that PSU. There is a reason its so cheap. Stick to the major brands (Corsair, OCZ, and Antec are popular choices). You also don't need one that powerful. 650W should be enough.
  2. MOBO: http://www.newegg.com/Product/Product.aspx?Item=N82E16813128392
    $40 cheaper after MIR and it supports ddr3

    RAM: use that money you just saved and pick up some ripjaws

    PSU: you don't need 720w. Also, the general consensus is that you should stick to a brand name psu (which I dont think enermax is)

    Also, just read that you wanted to crossfire in the future. The board I had listed does not support crossfire, but these do:

    x8 x8
    http://www.newegg.com/Product/Product.aspx?Item=N82E16813131402
    x16 x16 but obviously more expensive

  3. +1 to the AM3/DDR3 suggestion. You don't want to use AM2+ and DDR2 on a new build.

    I wouldn't waste your money on that PSU. You can get a better quality unit for less money. Here's a couple options:

    CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply - Retail $119.99 - $10 MIR

    http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=4017&Description=pc%20power%20and%20cooling%20750w&name=%24100%20-%20%24200

    The 4870 is a bit light for a 24" monitor. You could take some of the money saved and put it towards a 5850 if you can find one in stock.
  4. Also, just saw batuchka's response. Love the x3 720 & 790gx combo discount. Most likely cheaper than what I have listed.
  5. thanks for the feedback

    I will definetly go for the cpu/mobo combo that batuchka's recommended. Figure it would've been cheaper going with AM2+ since DDR2 was cheaper
  6. DDR2 RAM is actually not cheaper than DDR3 RAM anymore. There is absolutely no reason to use DDR2 on a new build.
  7. Another question, in looking at PSU, If i'm looking to crossfire the 4870, do i need a PSU to have 4x6 PCIE? Can i get away with a PSU that has 3x6 PCIE and use a molex to 6 PCIE adapter?

    I'm aware amps on the +12V comes into play, so does anyone know the math behind that? thanks again
  8. I still wouldn't get that Enermax PSU. All the PSU's I recommended above have at least four 6-pin PCI-E power connectors. I wouldn't use a sub-par PSU and cheesy adapters when you could just get a quality PSU with enough connectors.
  9. Shortstuff, I was actually talking about the Antec Earthwatts 650W. Its listed as a ATI certified for 4780 CF, but only has 2x6 PCIE
  10. I wouldn't use an EA650 for crossfire 4870's. I would either step up to a quality 750W PSU or use a 5770 GPU. The 5770's only require a single 6-pin power connector and use considerably less power than a 4870. An EA650 would power Crossfire 5770's just fine.
