im going to build a new pc
budget around 900 since its almost black friday so im expecting some good deals
these are the parts im thinking to buy
cpu: i5 2500K (probably gonna try to OC abit later)
mobo: gigabyte ga-Z68XP-UD4
graphic card: AMD Radeon 6870? or 6850?
RAM: 8GB or 16GB?
power supply: what brand and how much Watt do i need to efficiently juice up my pc?
case: cooler master storm enforcer
i already have HDD and CD/DVD room from my previous pc...
but thinking to get a small size (250GB) HDD at 7200RPM for cheap for operating system
Graphics card should be either HD 6850 or GTX 460(those 2 are the same price, and really cant go wrong with either. Id probably go with the HD 6850, but thats a hard decision) But if you want to spend a little extra then go with the HD 6870 for sure.
Power supply IMO for your case just make sure it is 650 - 750 watts(you should be able to get away with 650) and is 80 PLUS Certified BRONZE and has good reviews to make sure you are actually getting a solid PSU. That will be the best way to keep cost down.
Last thought...if you are gonna try to OC later make sure to get a cooler. If you count that in the budget now then look at one around $25-$30 like the CM Hyper 212+.
