I need a bit of help in deciding the configuration and correct pricing for the PC:

Quote 1: This one is with processor “Intel i7 4930K Unlocked (6 x 3.4 GHZ)”
Computer Case: Black ATX Tower Case
CPU: Intel i7 4930K Unlocked (6 x 3.4 GHZ)
CPU Cooling: Intel Heatsink & Fan - Low Noise
CPU Compound: Standard CPU Compound Supplied With Heatsink
Memory: Corsair Vengeance LP 32GB 1866 MHz (4x8GB) - Lifetime Warranty (DDR3)
Graphics Card: 1 x NVIDIA GeForce GTX 750 - 2GB - (EVGA) - Superclocked - (PCI-E)
Power Supply: Corsair 450W PSU - Low Noise
Motherboard: Asus P9X79 (Intel X79)
Hard Drive #1: 1 TB Seagate (1000 GB) SATA-III HDD 7200 RPM 64MB
Operating Systems: Microsoft Windows 7 Professional 64 BIT (Genuine DVD & COA Included)
Monitors: 1 x 24" HD LED Widescreen Monitor - Black - 2ms - 1920x1080 - DVI/VGA
PRICE: £1453

Quote 2: This one is with "Intel i7 4930K Unlocked (6 x 3.4 GHZ) OVERCLOCKED UPTO 4.4 GHZ" and as a result of this overclocking, the first three components (highlighted in red) need to be changed due to compatibility issues.
Computer Case: Aerocool X-Predator X1 Devil Red
CPU: Intel i7 4930K Unlocked (6 x 3.4 GHZ) OVERCLOCKED UPTO 4.4 GHZ
CPU Cooling: Coolermaster Hyper 212 Evo - Low Noise
CPU Compound: Standard CPU Compound Supplied With Heatsink
Memory: Corsair Vengeance LP 32GB 1866 MHz (4x8GB) - Lifetime Warranty (DDR3)
Graphics Card: 1 x NVIDIA GeForce GTX 750 - 2GB - (EVGA) - Superclocked - (PCI-E)
Power Supply: Corsair 450W PSU - Low Noise
Motherboard: Asus P9X79 (Intel X79)
Hard Drive #1: 1 TB Seagate (1000 GB) SATA-III HDD 7200 RPM 64MB
Operating Systems: Microsoft Windows 7 Professional 64 BIT (Genuine DVD & COA Included)
Monitors: 1 x 24" HD LED Widescreen Monitor - Black - 2ms - 1920x1080 - DVI/VGA
PRICE: £1558

I have two questions:
1) Is the configuration (6 cores, 32 GB RAM etc) alright to comfortably run CFX/FLUENT? It would be mostly used for porous regions, vortex shedding analysis and a multiphase simulations, covering both steady and transient simulations.
2) Is the £100 increase in configuration due to overclocking reasonable?

Thanks a lot!
