-Could easily play on High/Ultra settings on games you listed
-Could use a beefier GPU
-Could easily max out titles you have listed
-Very nice upgrade path available
-Dual core CPU apposed to Quad Core
-No overclocking capability due to Locked CPU+skimpy power phase on Motherboard
-Very nice upgrade path, however, it may end up costing more to go this route than to choose a beefy CPU from the start
**Radeon HD7950 over GTX660Ti**
With the recent price drop, there is no reason NOT to go with a Radeon HD7950 unless you NEED CUDA or PhysX. The HD7950 has great potential when it comes to performance when OC'd. Still a great performer not overclocked and matches GTX660 Ti performance.
Personally I would consider spending a little bit more $$$ with Option 2 and maybe put in a Z77 board. It will bring the total cost to around $830 but it will leave you with a much broader upgrade path (option to get K sku CPU's to OC in the future).
Why did you put a Hyper 212 EVO in Option 2 when you can't OC the CPU?
The Hyper 212 EVO is an option with list #2. You can take it out if you wish to give you more budget headroom for a difference piece of hardware if you so wished. I left that in there due to the possibility of an upgrade in the future
g-unit's build is great as well TBH. Quad core+Beefy GPU, quite a nice deal
