hey all, so my friend bought himself a custom built computer around 4 years ago, and back then it was like a supercomputer (i7 860, HD5800, etc.) but now he wants to upgrade, and he asked me to help him. His budget is $1500 but he'd like to spend as little as possible. I have already recommended a new CPU, Motherboard, RAM, and optionally a case. parts I recommended: CPU: intel i5 3570K ($239) CPU watercooling: Corsair H100 ($149) Fans: Noctua 120mm 1300RPM P-fan ($25) (for the corsair H100) Motherboard: ASUS P8Z77-V LK ($169) RAM: Corsair Vengeance CMZ8GX3M2A1600C9 8GB (2x4GB) ($65) Case (optional but recommended): Corsair Obsidian 650D ($203) TOTAL (without case): $627 TOTAL (with case): $875 He is getting a GTX 680 or a 670 in a few months, so thats why its not on the list right now. would appreciate anybody's opinion.
