The i7-920 will have better performance, and can overclock better if you want. The price delta of the whole system will be about $100 more than a comparable Qxxx system.

intel core i7-920

and another question can you suggest me a graphics card in the same budget??

hello again.i have checked the internet for desktop parts and i have made the following choices:

case-NZXT LEXA RedLine Edition Case (LEX-201)
power supply-PC Power & Cooling Silencer S75QB-EU Black PSU (750W)
cpu-intel core i7-920
cpu cooling-Scythe Mugen 2 Cpu Cooler (SCMG-2000)
motherboard-Gigabyte GA-EX58-UD3R (s1366, DDR3, X58)
RAM-Corsair 3GB DDR3-1600 Ram Kit (3 x 1GB, PC3 12800, 9-9-9-24, TR3X3G1600C9)
graphics card-EVGA GTX 275 (896 MB, PCI Express) or the Sapphire 4890 SVGA (PCI-Express, GDDR5, 1G)
hard drive-Western Digital Caviar Green 1TB HDD (32MB Cache, Sata, WD10EADS)
optical drives-Samsung 223QRSMN DVD-RW (Sata, Lightscribe, Retail)

So tell me if everything is ok,i mean if motherboard fits with cpu kai the power supply is enough for the graphics card and all other parameters.if anything is wrong suggest me another one but also taking care of the prices.i want to know if the desktop will have a good perfomance in everything i don't want the perfect desktop but a desktop that it wont make me wait and it will can run most games.also i would like to know the ways that i can make the desktop more cooler from high temperatures and which parts do this???
thank you for yout time....

^ +1. Also, what OS are you going to be using? If 64-bit I'd go with at least 6GB of memory instead of just 3..

i am going to use Genuine Microsoft® Windows® Vista™ Home Premium Edition Dual Greek/English

Is that 4 front usb ports that you want?
Is there a particular reason?
Most cases will have two in front, and room for all that you want in back.
Would a simple 4 port usb extension hub suffice? It might increase your chances of finding a good case.
Do you want quiet? room? Bling? cooling? portability?

i want to have 4 usb ports because my mouse and keyboard uses usb and then because i have wireless internet i think that i am going to need more.so you tell me that the most cases have 2 usb ports in front and another two on their back???the case NZXT LEXA RedLine Edition Case (LEX-201) has two usb ports in front and another two in back???

Every modern motherboard will have 6 or more usb connectors in the back. Every case that can mount that motherboard will handle as many usb or other ports that are on the back panel of the motherboard. The usual reason for front usb ports is to be able to conveniently plug & remove a usb thumb drive, camera, or a usb backup external drive.

hello there. i would like to have your opinion between two processors the intel core i7-920 and amd Phenom II X4 955.i know that clock speed is much more than the intel
but i can't understand the price difference?both have 4 cores the intel has 2.66Ghz and the amd has 3.2GHz and the price difference is big.why is that?is the amd Phenom II X4 955 inferior to intel core i7-920?

Wit my personal experience and from the reviews, would like to recommend you to opt of intel core i7-920. It is better then the best.
Please refer to the below links to know about it's overview.
