Core i5-750 gaming build advice


SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming (Company of Heroes, MW2, etc) CAD work, Movie Editing

PARTS NOT REQUIRED: Case (Coolermaster HAF933), OS HDD, DVD drive, Keyboard, mouse, speakers



PARTS PREFERENCES: Intel CPU, no preference for GPU

OVERCLOCKING: Maybe a little

SLI OR CROSSFIRE: Maybe in the future, prefer a single card solution

Hi all,
I'm updating my old gaming box and had this in mind. Please look it over and provide your ample expertise. I don't really have a budget but don't want to just spend money...

CPU: Intel Core i5-750 Lynnfield 2.66GHz 8MB L3 Cache LGA 1156 95W Quad-Core Processor - Retail

MOBO: ASUS P7P55 WS SuperComputer with NF200 LGA 1156 Intel P55 ATX Intel Motherboard - Retail
Xtreme Design 2 x PCIex16@x16 for 2 or 3 ways SLI support

PSU: COOLER MASTER Silent Pro 700 RS-700-AMBA-D3 700W ATX12V V2.3 SLI Certified CrossFire Ready 80 PLUS Certified Modular Active PFC Power Supply - Retail

RAM:( I have no real opinion here)
CORSAIR XMS3 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMX4GX3M2A1600C8 - Retail
Perfect match for Core i5 & Core i7

Data HDD: ( I have no real opinion here)
SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

CPU Cooler:
Need advice

GPU: ( I am totally open as far as manufacturer goes, but like the numbers Tom's gave this card)
SAPPHIRE 100282SR Radeon HD 5850 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card w/ATI Eyefinity - Retail

I think that's it. I'm considering this monitor:
SAMSUNG 2243BWT Matte Black 22" 5ms Widescreen LCD Monitor w/ Height & Pivot Adjustments 300 cd/m2 DC 8000:1(1000:1) w/ HDCP Support & 2 Built in USB Ports - Retail

Thanks in advance....

    looks pretty hawt!

    i'd go with cheaper stuff because i'm on a budget!

    5850 sapphire is definately the way to go (best bang-for-buck)

    i'd get a cheaper psu, like the 650tx corsair (90 bux and a 20 rebate)

    and i'd get G.Skill ram because it's recommended everywhere ($94 one)

    G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600
    (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL - Retail $94

    i'd get a cheaper mobo, because the one you're planning is wicked pricey. check out the
    MSI P55-GD65 LGA 1156 Intel P55 ATX Intel Motherboard - Retail $160

    wicked one-button overclocking = win, plus it's over 50 bux cheaper.

    im not familiar with monitor decisions, i have an old samsung 2ms 3000:1 SyncMaster 206BW and it runs 1680x1050 like a pro.

    the 650w corsair should suffice watt-wise shouldn't it? it's not modular, but you can throw them cords in the back.

    be sure to get a Hyper 212 plus cpu cooler, i heard it's leet for 30 bucks
  2. the g. skill ram does look good...
  3. If your just running 1 gpu a 650 is plenty but if you want to add one later with crossfire I'd go up to 750W

    +1 for g.skill they work fantastic

    for a monitor that is a little cheaper and I think better for it
  4. ^+1 PSU suggestion

    RAM: Corsair Cas7 RAM for $5 more than your listed RAM...
    CPU & MOBO Combo for a $25 savings...
  5. Just a heads up, you're not going to be able to run RAM at more than 1333 MHz unless you OC your CPU. The i5 750 only allows a memory multiplier of x10. With the stock BCLK of 133 your max memory frequency is 1333 MHz.

    If you get 1600 MHz RAM there may still be some advantages - you might be able to run it at 1333 with tighter timings or with less V so there may still be some value there. And it will have the extra headroom if you do decide to OC. (Of course 1333 RAM is OCable too you just aren't paying for the manufacturer guarantee.)

    A lot of people get 1600 with an i5 750 and then are upset when they have to OC their CPU to get to 1600 MHz so I thought I'd warn you now.
  6. Excellent!
    Thanks for the heads up on the CPU/Mobo combo.
    I think I'll go with the G. Skill Ram after reading a bunch this AM.....
    When I did a quick calculation for the PSU, it seemed that 700W would be sufficient even if I wanted to XFIRE later, but from your posts above, I may need the extra 50W.
    How about:
    Thermaltake Toughpower XT W0229RU 750W ATX12V V2.3 80PLUS BRONZE ATI CrossFireX Certified AMD GAME READY FanDelayCool Modular Power Supply - Retail

    Thanks for the input..
  7. thanks to all for your input. I ended up with the G. Skill Ripjaws Ram (4GB) and switched to a thermaltake 850W modular PSU so I'd have no worries when I crossfire later.
    also went with the 23" monitor that kroeters suggested.

    I'll let you know how it all works in about 3 days.
