So these are the specs for a gaming PC I want to build:
Azza Solano 1000 Black ATX Full Tower Case
Corsair TX750W 750W ATX 12V 60A 24PIN ATX Power Supply
MSI P67A-G45 (B3) P67 ATX LGA1155 DDR3 2PCI-E16 3PCI-E 2PCI SLI CrossFireX SATA3 USB3 Motherboard
G.SKILL Ripjaws X F3-12800CL9D-8GBXL 8GB 2X4GB DDR3-1600 CL9-9-9-24 Memory
Radeon HD 6870 Dual Fan 900MHZ 1GB
Seagate Barracuda ST31000524AS 7200.12 1TB
Intel Core i5 2500K Quad Core CPU
Noctua Nh C12P-SE14 140MM Heatsink
I already have a screen, mouse, keyboard, speakers, and windows 7. This build come out to about $850 CAN. Anyway to make it cheaper without sacrificing power or is this a good deal?
Secondly, you don't need so powerful PSU even if you go for dual-gpu setup in the future. There's a very good deal at Newegg with a PC Power and Cooling 80+ Bronze 650W PSU along with a Samsung Spinpoint F3 1TB
PC Power and Cooling Silencer Mk II PPCMK2S650 650W ATX12V v2.2 / EPS12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply
SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive
As for motherboard. I will choose a better motherboard with the latest Z68 chipset with the Smart SSD future. It has 8x / 8x SLI so you can add another 560Ti later and get perfomance close to one 580 (or even better).
