    Hi.
    I'm going to build my first desktop that's basically for gaming, I will need some advice on choosing the best hardware that's for gaming and my first time overclocking.

    CPU: intel core 2 Q9950(heard u can overclock to 4ghz)
    Motherboard: asus P5Q3(heard this motherboard have easy overclocking system and can OC very good)
    GPU: maybe hd4870 2x, or 2 of hd4850 or 2 of hd 4870 (which of them do u suggest?, but I think the hd4870 2x fit the asus P5Q3 motherboard more)
    Memory: Corsair ddr3 4gb 2x2 1600mhz or OCZ Platinum 4GB (2 x 2GB) DDR3 1600. If u suggest another one which one would it be?
    Case: Antec twelve hundred (I heard this case is very good for gaming and got nice cooling system but I have doubt, if this will fit with the motherboard and if it will actually have enough space for later maybe will do a quad crossfire?)
    Hardrive: 500gb seagate sata 2(maybe 1tb or 2 of those 500gb going to check the prices between them)
    PSU: 750 or 1000 watt? (so which PSU should I use for this rig? and does the PSU helps overclocking better if the PSU have more watt?)

    Have a nice day thanks in advance :).

    cpu wise, for gaming, a duo core is a better choice right now, I suggest the e8500

    graphics, if you want the best, get the 4870x2, no other single card can equal it's performance right now.

    PSU, a 750 watt corsair or pc power and cooling will be more than enough

    That case has enough room to for you to do whatever you want with it.

    Everything else I didnt mention is good choices IMHO.

    BTW, welcome to TPU

    The 4870x2 is the best choice since for you all crossfire is done on the card you wont need to worry about anything. If you have the $$$ then go for that.

    The Q9550 can hit 4Ghz but you'll NEED a good cooler to do it. I'd say get a good C2D dual for now and learn how to OC first. Learn how to build a watercooling loop and then get the Q9550. Or you can just get the Swiftec H20 220 and watercool the quad now for $160. My point is running that quad @ 4Ghz deserves/requires really good cooling.

    For the PSU BarbaricSoul is right PCP&C 750w or Corsair TX750w... up to 750w the TX from Corsair is the best model worth purchasing. If you plan to run 2 x 4870x2 you will need more power.

    I'd pick an X48 based motherboard for a DDR3 based rig..

    Go with E8500 if you want to jump on the overclocking wagon..

    Your chosen memory is perhaps a little on the slow side for serious OC'ing.

    How do you plan to cool this sucker? Remember to get an equal amount of air in and out of the case, and keep cabling neat.. The Antec 1200 is fine, a good alternative is the Coolermaster HAF..

    And yeah, I agree with the 4870x2 card, and a good 750-850w psu..

    The HAF is a great alternative to the Antec 1200... in fact I chose it over the 1200.

    I have the HAF 932 (check sig), absolutely awesome case :D

    In terms of PSU, get a Corsair TX750W if you're going to use a single 4870x2, or the Corsair HX1000 if you decide to Crossfire the x2's.

    Also I'd recommend Samsung F1 hard drives, extremely fast and quiet, can't beat that :)

    I'll agree with the dual core processor. Maybe look into getting a Tuniq tower 120 for cooling. Never take the board's vcore above 1.55v.

    OCZ plat for the ram, and even an OCZ gamerXStream PSU. They have an 850watt one that you'll be very happy with. http://www.newegg.com/Product/Product.aspx?Item=N82E16817341003

    Otherwise good setup. Although, I might get a faster smaller hdd for the operating system, then install and run your games off the 500gb.

    Is the performance of Q9550 better than e8500 at resolution 1920x1200?
    Will I be able to overclock the Q9550 to around 3.7ghz-4ghz with just the cooling fans in antec 1200?(I read some article there someone overclocked it to 4ghz with just cooling fans)
    what about e8500 how much can I overclock it with just cooling fans?
    I will probably pick the e8500 since its close to 100usd cheaper than q9950 but if the performance of Q9550 is better I will think about it.

    hmm since 750W PSU wont be enough if I'm going to do a crossfire, how much Watts will I need to crossfire 2x, 3x and 4x of hd4870 x2, ? (good to know, as I will do crossfire 2x of hd4870 x2 when the price drops a bit more)

    I'm new with overclocking and have never built a desktop before. About the cooling system for this desktop, I'm thinking about just using the fans from antec 1200 and maybe put 1 more 120-200mm fans on the side. Would that be enough?

    btw whats so good with OCZ ram and psu?, I have read alot of articles that says alot of good things about the corsair ram and psu good price and overclocking.

    Good idea, I havent done any research about hdd but which hdd is faster than sata 2? and how huge is the different between the faster HDD and a sata 2? Price wise too, is it worth getting?

    Thanks everyone for all the advices/tips/replies!

    The q9550 is a great CPU if you need the 4 cores. Currently a strong dual core CPU will be more than enough for gaming especially once overclocked. You COULD overclock with the fans provided but its NOT a good idea especially for the quad. Intel provides a fan for the CPUs that is designed to handle the temperatures @ stock speed. Once overclocking you can pretty much throw that fan in the garbage. Running the q9550 @ 3.7 on the basic intel fan is a bad idea.

    If you decide to get the E8500 you will easily save enough $$$ to purchase a good/great air cooler and then you could easily hit 4-4.5Ghz which would be perfect for gaming at 1900x1200. Unless you setup a watercooling system you wont get a q9550 to the same speeds you can get the E8500.

    If you want to crossfire 2 x 4870x2 get the Corsair HX1000 or something like that.

    Corsair and PC Power & Cooling PSU's are some of the best on the market right now. As I said before, since you plan to Crossfire with the 4870x2's later down the track, pick up the Corsair HX1000.

    And about the hard drives. SATA 2 is just an interface (its how the HDD conects to the computer, in this case its a SATA 2 cable). The only thing faster than a SATA 2 HDD is either a Solid State Drive (they still connect using SATA 2 but are much faster than traditional hard drives. Insanely expensive however.) and an SAS setup, which I would not recommend for a first build, also quite expensive.

    Some of the fastest SATA 2 HDDs you can get are the WesternDigital Velociraptor's, Samsung F1 and Hitachi Ultrastars.

    And you will need an aftermarket cooler, this one is one of the best performers around and is pretty cheap: http://www.newegg.com/Product/Product.aspx?Item=N82E16835233023
    If you get that cooler, you'll also need this retention brack to get the best possible mounting on an Intel motherboard.

    Hope that helps, Jmatt

    Wont it dmg my rig alot if I use 1000watt PSU on my rig that doesnt have crossfire atm?
    About ddr3 memory whats actually better timming: 7-7-7-24 is it better if the timing are less or better if its higher?
    Which brand of radeon hd 4870 x2 should I take, asus, ati, saphire, diamond, gigabyte etc? I don't think this matter but just in case, maybe the quality between those brand are huge.

    I will get the cpu aftermarket cooler and what about graphic card aftermarket cooler, do I need one? If yes which one should I get for my hd 4870 x2? Zalman VF1000 LED Heatpipe VGA RAM Heatsink or the Thermalright HR-03 Plus or Thermalright HR-03 GT?
    Atm I have 8 case fans(7 of 120mm and 1 of 200mm)
    Thanks again :)

    You wont damage your system with a more powerful PSU. The system will only draw the power that is needed and the PSU will only output the power that is required.

    For RAM the lower the timing the better.

    You dont need another cooler for the card....
