Gaming pc for your macbook (780 gtx)

Description:

I have a decent gaming pc to go. The specs are -

nvidia 780 gtx classified
i5 3570k oc to 4.4ghz + Xigmatek Dark Knight Night Hawk Edition cooler
1 tb hdd
650 watt corsair psu (decent psu)
cm storm enforcer case
Asus P8Z77-V
RAM: 8GB Corsair 1600mhz Vengeance (2x4GB)

Its a real solid pc, can play pretty much everything maxed out. Perfect gaming setup, will post pics to you if it generates interest. I could add either cash or another swap on top depending on the model of macbook. The gpu is actually only 2 weeks old and I could show a receipt if needed, cost me 420 quid off amazon.
