  • Building a good desktop

    Hello everyone. I've started to build my new gaming desktop, and after lots of intense research, I finished with two options. They're both Dell, the xps 7100 and the xps 8100 (because of their performance/price deal). The systems are:

    XPS 7100:
    PROCESSOR
    GRAPHICS CARDAMD Phenom™ II X6 1055T
    ATI Radeon HD 5770 1GB
    OPERATING SYSTEMGenuine Windows® 7 Home Premium, 64Bit, English
    MEMORY8GB Dual Channel DDR3 SDRAM at 1333MHz - 4 DIMMs
    HARD DRIVE1TB - 7200RPM, SATA 3.0Gb/s, 16MB Cache
    OPTICAL DRIVE16X DVD+/-RW Drive
    MONITOR21.5" Dell ST2210 Full HD Monitor with VGA cable
    SOUND CARDTHX® TruStudio PC™



    WIRELESSDell 1525 Wireless-N PCIe Card
    KEYBOARDLogitech Cordless Desktop S520 Keyboard with LX5 Laser Mouse
    MOUSEMouse included with Keyboard purchase
    BLUETOOTHDell Wireless 365 Bluetooth 2.1 Module
    MODEMNo Modem Option

    PSU 460 Watts

    VS the XPS 8100:
    PROCESSORS

    GRAPHICSCARDIntel® Core™ i7-860 processor(8MB Cache, 2.80GHz)
    ATI Radeon HD 5770 1024MB GDDR5

    OPERATING SYSTEMGenuine Windows® 7 Home Premium, 64Bit, English
    MEMORY8GB Dual Channel DDR3 SDRAM at 1333MHz - 4 DIMMs






    HARD DRIVE1TB - 7200RPM, SATA 3.0Gb/s, 16MB Cache
    OPTICAL DRIVE
    MONITOR
    16X DVD+/-RW Drive
    21.5" Dell ST2210 Full HD Monitor with VGA cable

    SPEAKERSNo speakers (Speakers are required to hear audio from your system)
    WIRELESSDell 1525 WLAN PCIe card with11n mini-Card & external antenna
    KEYBOARDDell Studio Consumer Multimedia Keyboard
    MOUSEDell Studio Optical MousePSU 350 watts

    As I saw at the High end CPU charts, the 1055t goes to the 25th place, and the i7 860 is at 28. The cpu and the psu are the only true diference betwen them. The 7100 has a 460 vs a 350 on the 8100. Are they good systems configurations? Is the psu so important?

      The 350W PSU should be just OK, as long as you don't plug too much extra in the machine. 400+ would be better.

      I would pick the i7-860 only because not many applications or games can make use of 6 CPU cores in the 1055T. And the 860 should do better with one or 2 threads. But you probably won't notice much difference in day to day use.

        I would never recommend a wireless network connection to a gamer or anyone with a desktop. If its your only choice expect poor online play. If you are a hardcore gamer the HD 5770 will struggle to run the latest games on high settings at your monitors native resolution of 1920x1080. If you can live with lower resolution and or quality settings in game you should be ok. If not you will need a HD 5850 or higher or a GTX 460 or higher video card. The PSU's in both systems seem to be on the small side. The 350 watt in the 8100 would never power the higher end cards needed to run the latest games at 1920x1080 with all the eye candy.

        I went to Dell and built a few systems and it looks like your price range is $1400-$1600? You can get a much more balanced system going with an AMD powered Dell. The AMD powered XPS 7100's are priced lower than the Intel powered XPS 8100's. The 7100's can be optioned out with a HD 5870 the 8100's are limited to a HD 5770. The six core Phenoms are clocked slower than the 4 cores and since games today will not fully use four cores I'd opt for the higher clocked four core AMD Phenom II 945.
        A XPS 7100 with an AMD Phenom II 945/ HD 5870/ 8 gigs of ram plus extras you had in your builds would cost $1400. See screen shot below.

          This is kind of confusing to me. The 1055t has six cores at 2.8Ghz right? so that means 6*2.8Ghz=16.8Ghz? while the i7 860 has four at the same 2.8Ghz=11.2Ghz? and the x4 945 is at 3.0Ghz*4=12Ghz???

          Shouldn't I take the fastest one? That allows me to do more stuff at the same time, and if I'm only playing one game (without background apps), the turbo core on the 1055t can increase up to 3.3Ghz three of the cores?

            And then, there's this thing...:
            AMD OverDriveTM
            Adjust your processor, memory and graphics settings to push the limits with AMD OverDriveTM , which utilizes multi-threaded CPU tests for overall system stability. So you can focus on your game.

            And this other thing...:
            AMD Fusion II Utility
            With a simple touch of a button, AMD Fusion Utility for Desktop lets you temporarily shut down idle software applications so you can redirect processing power when you need it most.

              AMD Fusion II Utility
              This is exactly the type of utility that I unstall as soon as I get a new PC. Bloatware. In fact I would pay money not to have these kinds of utilities on a new PC.

              This is kind of confusing to me...
              You are assuming that both CPUs perform the same amount of work per clock cycle. And this is not the case. The Intel chip will do more calculations per core per cycle.

                Dell is limiting component choices do to power draw and possibly heat output. Small cases and PSU's do not allow for building a great gaming PC. If this was not the case a i7 860 and a HD 5850/5870 or GTX 460 would be the best choice and close to your price range. The only way I see getting around this is to buy a different brand PC or build it your self. The best option would be to build it your self. If you can't there are very few custom builders that are worth a darn IMO. The best IMO is Falcon Northwest. The only way to get a better PC is build it your self. The only problem is cost. You would be way out of your price range.

                I'll stick to my original recommendation.
