  1. Hello!
    I am going to buy a new gaming pc late this month or early next month. Below are my component options.
    CPU, & MOBO :- 1. i7 870, msi p55 gd 65
    2. i7 950 , gigabyte ga x58a ud3r
    3. i7 875k , msi p55 gd 65
    i7 950 system (including ram) will cost me $150 more if the price of i7 950 drops later this month. Will the performance be high enough to justify the higher price? What about their overclocking?
    Keep in mind that I wont upgrade my cpu for atleast 3 years. But I will upgrade gpu and may use sli or crossfire. So the cpu must not cuse any bottleneck. Plus x58a ud3r has dual 16x pci-e rails, supports tri sli and xfire. i7 875k setup will cost almost the same as the i7 950 setup. So which one is the best option?
    RAM :- I am a little bit confused about ram. Which is more important, speed or timing? Which will perform better? A 1333mhz with 7 sec timing or a 1600 mhz with 9 sec timing? If I choose lga 1366 setup, I am thinking of buying 3*1 gb kit for now and buy another one later. Will 3 gb of ram be too low for gaming? And how does 6*1 gb setup performs compaired to 3*2 gb setup?
    GPU:- Here is my gpu options and their prices in India....
    1. galaxy gtx 460 768 mb stock - Rs 11500 ($ 250)
    2. zotac and palit gtx 460 1 gb stock Rs 14500 ($ 315)
    3. radeon hd 5850 -Rs 16000 ($ 350)
    4. radeon hd 5870- Rs 22000 ($480)
    5. gtx 470 -Rs 22000 ($480)
    xbitlabs.com review shows that gainword gtx 460 (factory oced to 800 mhz) gives minimum fps simmiler to hd 5870. Considering zotac gtx 460 overclocks to 835 mhz, will it match the gainword in minimum fps? And how easy or tough it is for a first time overclocker to overclock the zotac card? And if I can find a gtx 460 factory oc at the same price of 5850, which one should I go for? Or should I buy a 5770 for now and wait for next gen card as none of current gen cards have enough juice to handle directx11 proprly.
    PSU :- corsair 750tx or 850hx. 850 hx costs $55 more. Does it has enough power to support 3 gpus? Are the extra pci e connectors worth any real use?
    CASE :- nzxt tempest evo. Its $25 cheaper than haf 922 and has all the fans preloaded. But does it has enough space for sli with a physx card setup?
    HDD :- seagate 1.5 tb 7200 rpm.
    OPTICAL :- dvd writer
    SOUND CARD :- ASUS xonar dx
    SPEAKER :- Suggest me a 5.1 speaker within $120. Listning to music is my first priority.
    KBM :- Suggest me a wireless combo wihin $100. Must provide comfortable gaming.
    MONITOR :- Suggest a 24 incher with hdmi within $200
    Give your opinions and advices about my build.
    Thanks.

    Hi spac18. I assume you're from India. Just give us your maximum budget and we'll recommend the best possible combination of components for your system.

    Yes I am from india. My budget is around rs90000 ($2000) including peripherals, but at that price I will be able to buy parts worth $1600 only because of high vat.

    Some nice changes are coming... by October 1. USB 3.0 will be out on most boards by then. Hard drives are taking a big leap, as are cooling and memory. Might be useful to wait a month.

    90K is a lot of money and you'll get an excellent system out of it. However, I'll urge you to spend intelligently. For the CPU + motherboard combo I personally would opt for these:

    Asus CROSSHAIR IV FORMULA
    AMD Phenom II X6 Processor [1090T Black Edition]

    As for the GPU, I suggest you check out the benchmarks online and weigh the advantages and disadvantages of going SLI / CF against a single GPU configuration. A single HD 5870 should be great but 2x HD 5850 or 2x GTX 460 is even more enticing.

    Get a good PSU (something like the Corsair 750TX should be the minimum so that you have enough headroom for future upgrades). Also, the extra PCI-E connectors provides greater flexibility during upgrades. Ensure that your case is big enough to house the H 5870, if you're considering one, as it's a long card. HDD cages may cause problems in fitting the card in.

    I don't think you'll get very good 24" monitors for Rs. 10000. You could look for 22" Dell's at that price point.

    Nah (leaving out my preference for the i5).
    Thats also true.

    Let me know if this would be out of budget:
    AMD Phenom II X6 1055T Thuban 2.8GHz Socket AM3 125W Six-Core Desktop Processor HDT55TFBGRBOX

    2x EVGA 768-P3-1360-TR GeForce GTX 460 (Fermi) 768MB 192-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

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

    G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7D-4GBRM

    ASUS M4A87TD/USB3 AM3 AMD 870 SATA 6Gb/s USB 3.0 AMD Motherboard


    Also, I'd get an SSD if possible.
    BTW I hate wireless mice/keyboards.

    But techspot review shows phenom ii x 6 lags behiend i5 & i7.
    @hellokitty
    the board you suggested has only one pci e 2.0 slot.

    Well I can give some recommendations as to min specs.
    Quad core cpu
    4gb Ram
    gtx 460-5770 min for vid card
    600W psu
    hard drive is always good to have more space but you want a 7200RPM one.
