Hi Guys, I'm looking at building my first gaming PC, I've come up with a couple of alternate specs and I'm unsure which is better (if either are any good). I'm not going to be playing anything really intensive (I have an Xbox for that) but I do want it to last me for a few years without too much in the way of upgrades. I think I'm going to be ordering from fiercepc.co.uk; I seem to be getting better value on there than on other similar sites. My budget is roughly £600, I have a monitor; but do need a keyboard and mouse included in that price. The first spec is: Aerocool Aero-800 Gaming Case - Black Intel Core i5 6600 Quad Core 3.30GHz CPU Stock Cooler NVIDIA GeForce GTX 960 4GB Graphics Card Gigabyte Ultra-Durable H110M-S2H Motherboard 16GB Corsair Vengeance LPX 2400MHz DDR4 Memory (2 x 8GB) 1TB SATA3 6Gbps Hard Drive 24x DVD / CD Re-Writer Aerocool Integrator 600W 80+ Power Supply 300Mbps PCI WIFI Card The second is: Fierce Nova Gaming Case - Blue AMD FX-9590 Black Edition 4.70GHz (5.00GHz Turbo) Octa Core CPU Stock Cooler NVIDIA GeForce GTX 960 4GB Graphics Card Gigabyte 970A-DS3P Motherboard 16GB Corsair Vengeance LP 1600MHz DDR3 Memory (2 x 8GB) 1TB SATA3 6Gbps Hard Drive 24x DVD / CD Re-Writer Aerocool Integrator 600W 80+ Power Supply 300Mbps PCI WIFI Card My main concerns are the Power Supply and the Cooler. I don't know how vital these are, or if I should be looking at investing more in these. Thanks in advance.
