Hey and welcome to the forums
. For your budget I'd recommend going with an intel processor as with your budget you can comfortably have one.
Here is my rough suggestion for you:
CPU: Intel Core i5-4670K 3.4GHz Quad-Core Processor (if you are just gaming there is little need to go for the i7 imo)
CPU Cooler: Corsair H100i 77.0 CFM Liquid CPU Cooler
Motherboard: MSI Z87-GD65 Gaming ATX LGA1150 Motherboard (solid motherboard, not the most expensive one, but as Tom showed recently, you can still get decent overclocks on it)
Memory: Corsair Vengeance 16GB 1600mhz
Storage: Samsung 840 Pro Series 512GB 2.5" Solid State Disk (super fast for all your games)
Storage: Western Digital Caviar Black 1TB 3.5" 7200RPM Internal Hard Drive (storage for stuff and backups)
Video Card: MSI GeForce GTX 780 3GB Video Card (quicker than a titan in some tests and overclocks really well)
Case: Fractal Design Define R4 w/Window (Titanium Grey) ATX Mid Tower Case (personal fave case, although you could go for something different)
Power Supply: Corsair Enthusiast 750W 80 PLUS Bronze Certified ATX12V / EPS12V Power Supply
Operating System: Microsoft Windows 7 Ultimate SP1 (OEM) (64-bit)
This is just a basic guesstimate if you wanted to build something asap, you'd probably do better to wait for the new AMD cards as stated by others.
