Build up my own system

Hi, guys

I've just stand on the decision of building new Desktop for gaming. Hence, I came up with some odd questions. I am lacking of some important experiences because of long-time off reading. So, I post it here wait for someone mind sharing.

The "criteria" for system: Integrity (means as less of constraints as possible) and Efficiency. My Budget is about 700 - 800 (not include monitor and other peripherals), but I don't mind if the cost can reduce less than that. :D

1. Which system should I choose at current time, Intel or AMD, base on both price and performance relatively? It must be Quad core CPU. I prefer AMD, but I appreciate if someone give me some experiences about Intel as well. I see that Intel has just put up in the market the series i-x CPU, 32nm, but price is really high. I care about the performance compare to the price of similar AMD CPU. I still know that next week will be the advent of new AMD's motherboard chipset 8xx, is there any affection to the whole new performance of current AMD CPU like Phenom II X4 Deneb 955...
2. Do I need overclock, consideration on basis of relation between cost and performance of system? If yes, what should I need to care about the cooling system as well? It is not good idea if I spent too much on cooling overclocking system and the result received is just 5 - 10% increased in clock-rate, not on the whole system performance.
3. I need experiences on choosing motherboard thereof. Brand, chipset. Why is so much different in price of mainboard with the same type of North and South Bridge chipset? In my opinion this is the most important component of system, ensuring for Integrity.
4. For Integrity of the system, should I use graphic Card ATI or NVIDIA? Which one is better for game? What should I choose if I used AMD system? Are there any other option? (I like to play Role Playing Game, with highest quality for Resolution about 1600x900)
5. Is there anything I should pay attention on choosing RAM?
6. Are there anything else?

So, I am eager of waiting reply from pro-guys. Thank you so much for spending time answer my question.

  1. Hi: Well AMD processors are currently at a performance disadvantage
    to Intel processors, although AMD processors are also less expensive
    than Intel processors, so you may lose 5-10% performance, but drop
    20-30% off the price. Based on that, I would suggest AMD if you don't
    have a fortune to spend.

    Regarding the video card,I would suggest An a Radeon HD 4870 or ATI 5770 Based on your budget and needs

  2. Thanks for your suggestion, Greenfield.

    Is there any different in mainboards between 790GX chipset and 790FX chipset, beside the onboard video card? Why do we have to use such a "big" case like this? Do we need extra cooler device for entire system? Can I use Phenom II X4 Deneb 2.8 ($139) instead, if so, what type of motherboard should I use? I notice there is some type of mother board that support specific for (ex: or ). Is there alternatives of Intel System instead?

    Please help me to answer those question once.

    Thank you so much for reading and spending time for reply.
