Need help with Gaming PC.

[BrownieTopper]

So I want to build a gaming PC. I have an office PC and it specs are:
Case: Case that comes with Lenovo ThinkCentre Edge 72 (http://www.newegg.com/Product/Product.aspx?Item=N82E168...)
PSU: 260W
CPU: Inter Core i7-3770 3.40GHz
RAM: 16GB DDR3
GPU: Intel HD Graphics
Motherboard: Intel H61

I was thinking of using this computers CPU and RAM and buying a new case, psu...
What do you recommend? i want to use bitfenix prodigy case if that is possible? My budget is 1000$ and i would reather get Nvidis GPU than AMD.

Prodigy is only compatible with ITX sized motherboards. It might not be possible. Try this one

For psu, go with this; http://www.newegg.com/Product/Product.aspx?Item=N82E16817139011

And NVIDIA gpu? What level of performance are you looking for? A 770 might cut it. http://www.newegg.com/Product/Product.aspx?Item=N82E16814130921

What about Motherboard?

How much are you willing to spend on a motherboard? I'd recommend a Z77 board, so as you can take full advantage of Lucidlogix's virtu mvp, which can boost gaming performance.
