Found an excuse to build an I7 System. Need Help

I was thinking of building a new system anyway, so when my motherboard went dead I decided it was time.


What I have already and am willing to use.

COOLER MASTER eXtreme Power RP-650-PCAR ATX
http://www.newegg.com/Product/Product.aspx?Item=N82E16817171014

Western Digital Caviar SE16 WD3200AAKS 320GB 7200 RPM SATA 3.0Gb/s Hard Drive
http://www.newegg.com/Product/Product.aspx?Item=N82E16822136074

ASUS 20X DVD±R DVD Burner with LightScribe Black SATA
http://www.newegg.com/Product/Product.aspx?Item=N82E16827135156

APEVIA X-JUPITER G-Type X-JUPITERG-BK Black Aluminum ATX Full Tower
http://www.newegg.com/Product/Product.aspx?Item=N82E16811144205


My budget is $1100, unless the above parts will not work well with the new setup. If they can't, the budget goes up to 1400-1500. I would prefer either a 4870 or 4870x2 GPU or just 2 4870s. What I don't know is if my current power supply will work with an I7 setup and one of those cards. I would think it would be fine for the 4870, but the x2 might give it some problems.

So what I need advice on:

Motherboard?

Which I7 model?

After Market Air Cooler?

RAM?

PSU?


Thanks for the help.

    Your PSU is okay.

  2. See here for requirements:

    Certified power supplies are recommended. Refer to http://ati.amd.com/certifiedPSU for a list of Certified products.
  3. Stay away from Coolermaster PSUs other than Real Power Pro 850W+.
  4. I'm thinking about crossfiring 2 4870s. I think I'd better be on the safe side and upgrade to at least 800W.
  5. Does it have to be i7?

    If you play on a 24" or larger monitor, the same budget buys you mediocre performance with i7 920/X58/6GB DDR3/HD 4870, or great performance with Q9550/GA-EP45-UD3P/4GB DDR2-800/HD 4870 X2.

    I would focus on the graphics card and cut back on the overpriced x58 and DDR3. Even the Q9550 won't be used at 100%.

    I had a 22" and a 19" on my now defunct system.

    I figure if I'm going to be building new, I might as well look towards the future.
  7. All right. If you want a cutting-edge system and have the cash, why not.

    You could try a GA-EX58-UD3R ($185) with i7 920 and NH-U12P (the LGA1366 version).

    This RAM is known to work well with that MB:
    OCZ Gold 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit $170

    Now, the bad news is about the PSU. Your PSU is labeled incorrectly. It claims 650W but only delivers 18A+18A on the 12V circuit, and I'm pretty sure it's not even 36A combined. A real 650W PSU like Corsair's delivers 52A, for example. A 610W PSu like PC Power & Cooling's delivers 49A. I think your CoolerMaster would do for a HD 4870 1GB card, but not for a HD 4870 X2 or for HD 4870 1GB Crossfire. I'd recommend you get a PC Power & Cooling 750W. ($90)

    There's also the Corsair 850TX, $120. It may be worth it if you're planning to add lots of hard drives and a TV tuner or two and so on.
  8. The Cooler Master HAF-932 is a better case for less money, imho:

  9. It's $10 more, actually, right now at Newegg.

    But I agree, it's a better case and the change is a good idea. I like those huge fans :)

    ... depending on final load. Look at the Mail-In Rebates too,
    because sometimes you can get more wattage for the same or
    similar prices AFTER MIR.
