Check out my post in the High Performance/Gaming section named Intel Build for Gaming/Folding.

Or post this here, but I am sure mods will move for you.

I'd drop the RAM to 6GB, and get a better video card. If you want to game, the video is more important than the RAM, and the processor.

What about keyboard and motherboard?

--------------------------

Look at other threads. Take this one for example.
i7 Build Suggestions?

Processor: Newegg.com - Intel Core i7 920 Nehalem 2.66GHz 4 x 256KB L2 Cache 8MB L3 Cache LGA 1366 130W Quad-Core Processor - Processors - Desktops
Mobo: Newegg.com - GIGABYTE GA-EX58-UD4P LGA 1366 Intel X58 ATX Intel Motherboard - Intel Motherboards
RAM: Newegg.com - OCZ Platinum 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit Desktop Memory - Desktop Memory
PSU: Newegg.com - CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply - Power Supplies
HD: Newegg.com - Western Digital Caviar Black WD6401AALS 640GB 7200 RPM 32MB Cache SATA 3.0Gb/s Hard Drive - Internal Hard Drives

Then I'd add either a 295, or a 4890 video card.
Newegg.com - SAPPHIRE 100269SR Radeon HD 4890 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Desktop Graphics / Video Cards
Newegg.com - BFG Tech BFGEGTX2951792E GeForce GTX 295 1792MB 896 (448 x 2)-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Desktop Graphics / Video Cards

witch brand of graphic processing units is the best ? for Half life 2 and fallout 3 and orther good games ?

You picked a great brand, its just that the 4850 isn't exactly top of the line, while all of the other components are very close. Maybe look at the 4870 1gb and drop some ram.
