Re: motherboard HELP! plz
For RAM I know that G.SKILL is good (which I am using currently), CORSAIR is also recommended, OCZ I hear is fine. You should also get 2-4GB for a gaming system.
For video cards there is ATI and nVidia. Both are very good. Brands that make good cards XFX, Sapphire, HIS, EVGA, ASUS, VisionTek, PNY. I don't know much about nVidia but I know that any card in the ATI 4000 series would be good for you like the 4770 or 4850.
Now, are you building this whole thing from scratch? Which leaves a case, a hard drive, a dvd drive, a power supply.
For a case I would suggest Cooler Master
Western Digital makes good hard drives
LiteOn, Sony, Samsung make dvd drives
CORSAIR makes excellent power supplies.
Do you already have a monitor? and a keyboard and mouse?
