Edit 3:
I was going to go i5 + 5870 path, then asteldian kindly reminded me about the bottleneck of p55 usb 3.0 boards, I then went read a bit more about it and found out I will have to pay more to get the board with:
routing add-on components through PCIe switching logic or by physically wiring these controllers to PCI Express 2.0 lanes
which would cost more to an extent that it is only 71 pounds (around 90 US dollars in electronic exchange rate) cheaper than a i7 920 x58 based machine with tri channel boards/mem in place.
i5 750 system:
CPU: i5 750
mobo:Asus P7P55D-E pro P55
GPU: HD 5870
RAM: G-Skill Ripjaw 4GB DDR3 1600MHz CL7(7-8-7-24) 1.65V
PSU: Antec TruePower New Modular 650W Power Supply
HDD: Samsung F3 or Seagate 7200.12 x2 for RAID0
Total: 935 Pounds
--------------------------------------------------------------------------------------
i7 920 system:
CPI: i7 920
mobo:Giga X58A UD3R
GPU: HD 5870
RAM: Corsair XMS3 6GB DDR3 1600MHz Tri-Channel
PSU: Antec TruePower New Modular 650W Power Supply
HDD: Samsung F3 or Seagate 7200.12 x2 for RAID0
Total: 1006 Pounds
Difference: 71 Pounds
It is still worth it to go cost effective and go i5?
Or rather spend 71(90US) more for the mighty i7 tri system?
