Would I be bottle-necking my GPU with this CPU?

Hey guys,

Picking parts for my first custom rig, and I've gone through the list changing parts several times now. For one, I'm trying to keep the cost at ~$1,000 CDN. With the specs I'll list below (excluding peripherals which I already have, and an OS), it sits just under $1,000.

But I'm worried that I'm going to bottle-neck my video card with an i5 CPU. The i5 3570K is about $100 cheaper than the i7 3770 that I had contemplated getting before. I'm going to be using this PC for gaming, and editing and rendering video as well as real-time audio creation and playback, so high CPU and RAM speeds are pretty essential.

Intel Core i5-3570K 3.4GHz Quad-Core Processor (or i7 3770?)
ASRock Z77 Extreme4 ATX LGA1155 Motherboard
Corsair Vengeance 8GB (2 x 4GB) DDR3-2133 Memory
Plextor M5S Series 128GB 2.5" Solid State Disk
Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive
Sapphire Radeon HD 7850 2GB Video Card
Fractal Design Define R4 (Black Pearl) ATX Mid Tower Case
CoolMax 500W 80 PLUS Bronze Certified ATX12V / EPS12V PSU
Asus DRW-24B1ST/BLK/B/AS DVD/CD Writer

Total: ~$900.

Any other things anybody could suggest for my build would help, too.
Thanks for the help.

No bottleneck. If you don't plan to overclock, you can upgrade the GPU and lower some other parts.

No, that CPU will not bottleneck the GPU.

You should consider to save some money and buy a better graphics card by:
1. buy RAM with lower frequency, 2133 I don't think will make a difference in games.
2. Keep the i5 and save that $100
3. Lower your motherboard a bit.

Nowadays it's all about the graphics card that matters.
