My brother's BIL is into music composition and audition etc. He is looking to buy a new system (or build one). He was asking me if a Laptop will suffice for recording his compositions with good quality audio and video. He was looking to buy a i5 or i7 based Quad core + dedicated graphics powered laptop (with 8GB ram + 500GB Hdd). I suggested to build a Desktop powered with i5/i7 + dedicated grarphics and buy a real good $100 sound card and good headset. May be go little cheaper and build a AMD Quad/Hex based desktop. Is a Laptop good enough or desktop is better? If laptop suggest me few good ones. Looking for a mid-range priced ones (about $800).
