Hello everyone, I'm looking at putting together a new gaming computer. Here is what I've come up with so far: Motherboard: EVGA X58 SLI LE Motherboard Graphics card: Sapphire Radeon HD5870 / PowerColor Radeon HD5870 Power supply unit: Corsair HX-750 Power Supply Case: Lian Li Armorsuit PC-P50 RAM: Corsair Dominator GT PC3-12800 C7 6GB (3x2GB) DDR3 HDD: Samsung SpinPoint F3 1TB CPU: Intel Core i7 920 CPU cooler: Titan Fenrir CD/DVD: any I have several questions for those of you who are kind enough and have the time to answer. Firstly, will the motherboard fit into the case I have selected? A Youtube commenter claimed that it would but more reliable confirmation would be nice. The motherboard supports ATX and M-ATX... I personally do not know what this means, lol. Also, with regards to graphics cards, does the "maker" (unsure of official lingo, but I mean Sapphire vs. Powercolour, for example) make a lot of difference? From what I've read it seems bit-tech likes Sapphire products, but I cannot find them in stock and have found a Powercolour in stock. So I am wondering if I should wait or grab one now. Any other suggestions are welcomed! Please let me know if I've made glaringly bad choices, or forgotten something altogether. Thanking you in advance !
