guidelines for building your own pc
When you build PC for games, you'll need a minimum of core i3 or core i5, core i5 750 is better cpu, core i5 750 has 8mb cashe and 1333 Mhz bus rate. In case you have less price range use Core i3-540 Cpu.you may also improve your Computer to Intel Core i7 Processor chips.
There are 2 well-known brand names in motherboard these are ASUS and Intel, Intel is much more dependable than ASUS, but functionality wise ASUS is a bit more greater than Intel, attempt to selected ATX form element motherboard, also check comparability of board, if you'd like to used SLI than decided dual PCIe slot board. I recommend Intel H55HC and ASUS P7H55D-M PRO, it's great board as well as on very inexpensive cost. Both board are support as much as Intel Core i7 Cpus.
Attempt to select dual channel memory, Corsair XMS3 is better memory to quicker your computer, when you have less budget use standard cost Memory. If you utilize ASUS you may above clock your memory space.
Case & Power Supply
Antec and Cooler Master are great manufacturer is chassis, I suggest you Elite CM370 is better affordable casing, you may also use CM690 is better choice. For PSU calculate your all peripherals power consumption than select power supply. In my thinking 420W supply is perfect for over settings. If you've superior price range use branded supply like Cooler Master, Antec and Corsair.
Don't believe less expensive DVD burner, I suggest you Sony DVD burner
Disk Drive: Hard Disk Drive storage cache is most essential than thinking for capability, because your hard drive pace dependant on cache, I think nowadays in minimal capacity necessary is 500GB.
The most essential part of graphic card are Bits and Direct X support, around my considering minimal Bit for graphic card is 128, but extra is best, attempt to select new model and also, many of new games are coming up with issue on old cards. Manufacturer is a essential, make an effort to select XFX, EVGE and HIS, in order to opt for ATI, individually I'm a admirer of nVidia, 9800GT is great card, 512MB, GDDR3, 256Bit, Clock Rate 550MHz, High definition tv,DVI,DVI out put.
