Hello everyone. This is my first post and I wanted to know if someone could see if the parts I bought for my new computer are compatible to each other. I am new to this. These are the parts:- Processor: Intel core i3 2100 sandy-bridge 3.1 ghz 2x256kb l2 cache 3mb l3 cache 65w dual-core, Motherboard: Biostar h61ml lga 1155 intel h61 micro atx intel motherboard, Power supply: Antec bp550 550w atx12v v2.2, Case: NZXT gamma classic series 001bk steel w/ rear 120mm fan, Graphics card: Sapphire radeon hd 6770 1gb gddr5 pci-express 2.1 x16 crossfireX support, Ram memory: G.Skill ns 4gb (2x2 gb) 240 pin ddr3 1333 (pc3 10600), Hard Drive: Western Digital 320gb 7200rpm 16mb cache sata6.0gb/s 3.5... Did I miss anything important? Will all this work? Will this setup/rig get me medium-high settings with new games on a 720p monitor? How long will the build take? I will have my dad help. Please confirm if this will work, and if I need anything else or different for this setup. The parts all together costs me $470 w/ out the os. Please tell me if this will work. Thank you.
