Hello, my motherboards have been pretty weird this year, since i got the HD 4870, 3 motherboards died. So I am thinking about building a new pc, and I have found few goods parts for it. Processor: Intel Core i7 Processor, i7-920, 2.66 GHz, 8 MB, LGA1366 CPU, Retail Motherboard: Gigabyte, GA-EX58-UD3R, Core i7/ Intel X58/ DDR3/ CrossFireX/ A&GbE/ ATX Motherboard RAM: STT D3-1333, 2 GB/128Mx8 Samsung Chip Memory Power Supply: Thermaltake Toughpower W0104 650W w/14cm Fan Power Supply Hard Drive: Seagate, ST3500418AS, 500 GB, SATA2, 7200 rpm, 32 MB Hard Drive A new case: KÖNIG MICRO ATX CASE WITH LCD TOUCH SCREEN, model CMP-COMPCASE20 And a addational fan: KÖNIG 120 MM COMPUTER FAN WITH TEMP INDICATION, model CMP-FAN50TEXT So will those parts work together? And I think that the graphic card is good enough Radeon PowerColour 4870HD 512MB. I know that I have pretty low ram 2GB, but else I am out of my money and I am thinking about a guitar too. Do you recommend something else for about the same price? This is mainly a computer for gaming. Also, does the hard drive help in gaming? Thanks.
