Hi, i have never done anything with the computer hardwares, but i want to upgrade it on my own. My computer is HP Paviilion 4999t and the specs are Motherboard: ASUS IPIBL-TX Chipset: Intel G33 Express Front-side-bus (processor dependent):1066/1333 MHz Power output wattage: 350 Watt Processor: Core 2 Quad Q6600 (K) (2.4GHz /1066 MHz) 8 MB L2 cache Memory: 3 GB (2 x 1 GB, 2 x 512) DDR2 PC2-5300 Hard Drive: 750 GB 7200 rpm SATA 3G (3.0 Gb/sec) Graphics: GeForce 8600GT I want to upgrade my Memory to 8GB and Graphic card to GTX200 series.. and maybe the processor more specifically.. I want Samsung DDR3-1333 2GB Memory x 4 = $100 and a great graphic card that would work with sc2 full option. and maybe I7 quad core processor.. i dont want it to use too much electricity thou.. Any advice for this noob?
