Thinking of building a gaming computer... need advice


Aug 2, 2011
so i'm new to computers and i was considering building a PC to play games on. this would be used mostly for MMOs like guild wars 2 etc... and maybe some games such as Battlefield 3, dirt 3, etc... i don't want to spend a huge amount of money on this... maybe around 700-800$

what i have so far is this:

1. CASE: COOLER MASTER HAF 912 RC-912-KKN1 Black SECC/ ABS Plastic ATX Mid Tower Computer Case

2. RAM: G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9D-8GBRL

3. PSU:
Antec NEO ECO 520C 520W Continuous Power ATX12V v2.3 / EPS12V 80 PLUS Certified Active PFC Power Supply

4. GRAPHICS: GIGABYTE GV-R687D5-1GD-B Radeon HD 6870 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity

5. CPU: AMD Phenom II X4 955 Black Edition Deneb 3.2GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 125W Quad-Core Processor HDZ955FBGMBOX

6. MOBO: GIGABYTE GA-870A-UD3 AM3 AMD 870 SATA 6Gb/s USB 3.0 ATX AMD Motherboard

i'm not sure how well this will run modern games/ how high i could go on the settings. as for the OS i suppose i should get win7 64bit? or could i go with vista?

any help is appreciated :)


OK total cost for everything you need for your new pc including Windows 7 64bit, And a motherboard which will be future proof and be able to take the new AMD bulldozer cpus, = $807

The board you listed is 16x and 4x on the pci-e16 slots. I wouldn't go any lower than 8x/8x. I would also downgrade the HDD and go 8gigs of 2 4gigs of ddr3 1600.

I have to say i disagree, as he has massive room for upgrading by simply upgrading his gpu in the future rather than thinking of going xfire.

As for the Ram he can add another 2x2gb in the future at any time when he has the cash, where as a decent HDD is important from the start with regards over all system performance.
you dont need huge amounts of ram. 4 gigs will be fine as long as he gets at least 2 sticks for dual channel mode. a fast hdd is essential but the spinpoint has a flaw in that it doesnt like smal files and speeds drop rite down... i know as i have 3 of em.
they are good drives but only show there true performance in raid 0

as the above said you would be better going for an i5 rather than an amd. not because they oc better which they do, but beause clock per clock there more powerfull. at 3.0ghz the i5 sandy is nearly 40percent more powerfull than most amd phenom 2's

comes to 618usd leaving 200+ when you include rebates for the case and drives.
