I've had my current build for about 3 years. Unfortunately, my mobo's quit on me. Based on advice in the forum, rather than remaining locked to an old chipset, I've decided to upgrade both processor and mobo, and get a new case while I'm at it. With RAM so cheap, I'm thinking of getting some new RAM too. I'll be using my existing GFX card, and disk drives. Budget for the upgrade: approx £500 What do you think of this build: (existing equipment in blue, new in green) CPU: 3.4GHz Intel Core i5-3570K - £180 Motherboard: Asus Maximus V Gene - £150 Memory: 8GB 1,600MHz DDR3 - £35 CPU Cooler: Arctic Freezer i30 - £30 Case: Corsair Carbide 500R - £90 GFX: 2GB MSI HD 6950 Twin Frozr III Power PSU: Corsair 650W TX Series PSU - 120mm Fan, 80+% Efficiency, Single +12V Rail Storage: 1TB Samsung HD103SJ Spinpoint F3, S Storage: 2TB Seagate ST32000542AS Barracuda Storage: Crucial CT128M4SSD2BAA 128GB M4 SSD 2.5 inch Total: £485 Usage: Primarily gaming, at 1080p. I don't think i'll be overclocking, though I don't mind having the option. My PSU is about 3 years old, do you think that 650W is sufficient for this build?
