I am building this machine primarily for the use of flight simulators, though also to play other games like AC3, Dishonored etc. I fell as though stepping down to a 3470 might be the better option, considering then I could get a H77 board and use the stock fan. The only reason I havent done that is because flight simulators seem to be very cpu dependent, not gpu dependent. Anyhow, I live in Australia, so everything is so much more expensive, I saw a US build identical to this for $650. Everything is priced from umart.com.au sunshine coast branch.
RAM: G Skill 8G(2x4G) DDR3 1600Mhz PC12800 RL 9-9-9-24(CL9D-8GBRL) $45.00

CPU Cooler: Cooler Master Hyper 212 EVO w Transparent 12cm $36.00
PSU: Antec VP-550P 550W Strictly PSU $69.00
HDD: Seagate SATA3 1TB 7200RPM 64mb Cache $74.00
GPU: Sapphire HD7850 OC 2G 256Bit GDDR5 PCIE3.0 DVI HDMI 2*MiniDSP $220.00
Motherboard: Asrock Z77-EXTREME4 Z77/4 x DDR3/2 x PCI-E3.0/4 x SATA3/6 x USB3.0/HDMI $134.00
CPU: Intel Core i5 3570K LGA1155 CPU 3.4Ghz 6Mb Cache Ivy Bridge $229.00
With a 3470, I save $40 from the CPU, $35 from the cooler and $55 on the motherboard if I change it to the H77. Any suggestions would be appreciated!
