Hi guys, i've decided to build a new desktop computer. I build many before, but i had the same for years now, so i'm not really updated the new hardware technology.So i want it to be high performance, don't really need it for hardcore gaming, but i want to be able to connect it to a lcd tv and watch downloaded hd movies(do i need a media case??) . I also want to use it as a stereo, so i need a sound card that can support a dolby surrond system.I did some reserch and i was opting for a Intel Sandybridge i5-2500K , ASRock Z68 Extreme3 Gen3,G-Skill 8GBXL Ripjaws DDR3 PC12800 1600MHz 8GB. Do you think i'm going over the top? remember please that i will keep the computer 4/5 years before i will change it again.So if you can suggest any other cpu, motherboard and please give me some hints for video cards and audio cards. thanks Alex
