Also make sure nothing is currently assigned the IP your about to allocate, check in your router under currently attached devices to see whats been assigned.
Even then its not going to take more than a simple reboot of router.
Doubt that i7 930 is going any were just yet
Mines been overclocked to 4.3Ghz since just after Bloomfield launch, solid, no issues here but its been kept cool all that time under water.
Skylake looks ok if you just wanted to upgrade now though. Im just gona grab an X5670 off eBay in few weeks and run it high as i can until my mobo pops (5 years old) then upgrade
The one you linked....i doubt GTAV will even launch at all due to not meeting minimum requirements.
As for upgrades, likely out the window for a quad due to chipset used.
Its gona take something a lot more powerful to even start the game up.
An FM2 AMD quad at minimum i would say, i talk from playing GTAV on an AMD quad overclocked.
For peak as you say then i would say get an Intel i7 build?GTX 970/ 290X
