Hello guys. I'm building a gaming PC for the first time and I have a budget of $2.5k (includes monitor and keyboard also). Can top up a 1 or 2 hundred if really needed but prefer it to be $2.5k max. I went to reddit to get some feedback and one of the commenters suggested asking the question here since people at hardwarezone know the local market better 
Anyway this was my initial build but without monitor and keyboard:
CPU: Intel Core i5-4590 3.3GHz Quad-Core Processor
Motherboard: Gigabyte GA-Z97X-SLI ATX LGA1150 Motherboard
Memory: Corsair Vengeance Pro 16GB (2 x 8GB) DDR3-1866 Memory
Storage: Sandisk Ultra Plus 256GB 2.5" Solid State Drive
Storage: Toshiba 2TB 3.5" 7200RPM Internal Hard Drive
Video Card: 2 X Sapphire Radeon R9 290X 4GB Tr-X OC Video Card (2-Way CrossFire)
Case: Phanteks Enthoo Pro ATX Full Tower Case
Power Supply: EVGA SuperNOVA 1000G2 1000W 80+ Gold Certified Fully-Modular ATX Power Supply
Optical Drive: Lite-On iHAS124-14 DVD/CD Writer
Operating System: Microsoft Windows 8.1 - 64-bit (OEM) (64-bit)
But another redditor suggested this instead:
CPU: Intel Core i7-4790 3.6GHz Quad-Core Processor
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Motherboard: Gigabyte G1.SNIPER H6 ATX LGA1150 Motherboard
Memory: G.Skill Ripjaws X Series 32GB (4 x 8GB) DDR3-1600 Memory
Storage: Crucial MX100 128GB 2.5" Solid State Drive ($69.00 @ B&H)
Storage: Seagate Barracuda 2TB 3.5" 7200RPM Internal Hard Drive
Video Card: EVGA GeForce GTX 970 4GB SSC ACX 2.0 Video Card
Case: Fractal Design Define R5 w/Window (Black) ATX Mid Tower Case
Power Supply: SeaSonic 760W 80+ Platinum Certified Fully-Modular ATX Power Supply
Operating System: Microsoft Windows 8.1 (32/64-bit)
Monitor: Acer GN246HL 144Hz 24.0" Monitor
Keyboard: Cooler Master Storm QuickFire Rapid Wired Gaming Keyboard
So im not so sure which one is better for me. :/ My concern is mostly how much are the parts here and where should I buy my parts? Sim Lim Square or buy online is better? And which shops in Sim Lim are the better ones? So anyone can recommend me what parts to buy and where to buy them from?
PS. I wanted to post hyperlinks but for some reason I'm not allowed to. Oh wells.
