DDR3 1995.2 CL9 11-10-27 1T
ADIA64 Memory Read - 19509 MB/s
Sandra Memory Bandwidth - 24499 MB/s
MaXXMEM Memory-Copy - 20886 MB/s

In the test, I OC DDR3 8GB X2 from 1866 to 2000. You can see DDR3 performance is always Intel advantage.
The bandwidth is similar to Sandy Bridge, but DDR3 clock can rise 2~3 levels.
Previously, H67 only can reach DDR3 1333, but H77 max clock is DDR3 2000.
Of course, Z77 with better quality DDR3 can even achieve 2400~2600 which is enhance DRAM extreme clock a lot.

3D Performance Test
Intel HD Graphics HD2500
3DMark Vantage => P1783

StreetFighter IV Benchmark
1366 X 768 => 41.72 FPS

1280 X 720 => 709

i3-3220 builds in HD2500 and former i3-3120 or i5-2300 both built in HD2000.
For above three 3D software, HD2500 performance is 30~50% higher.
If HD2500 3D performance is not enough, you can choose HD4000 built-in or external VGA.

3DMark Vantage => P25923

StreetFighter IV Benchmark
1920 X 1080 => 238.46 FPS

1920 X 1080 => 4002

I use the mid to high end VGA to see how the performance is of i3-3220 with VGA.
Three 3D software is around 10~20% lower than nVIDIA GTX570 bundle with i7 CPU.
This can be the reference for limited budget. If you want to enhance 3D performance, you better to put you money on VGA.
i3-3220 can bring out around 80% 3D performance. If you have more budget, you can consider CPU either.

H77 also support Intel Smart Response Technology.
Also, GIGABYTE H77-DS3H has mSATA slot.
HDD performance test (Disable SRT feature)
ATTO DISK Benchmark max Read is 106.5 Mb/s and Write is 104.4 MB/s.
HD Tune Pro 5.00
64K - Read - Average 82.6 MB/s Access Time 15.2ms

HDD plus SSD performance test (Enable SRT feature)
ATTO DISK Benchmark max Read is 212.6 Mb/s and Write is 69.6 MB/s
HD Tune Pro 5.00
64K - Read - Average 151.9 MB/s Access Time 0.2ms

SanDisk U100 spec is mSATA and SATA3. The max Read/Write is 450/380MB/s.
Due to H77-DS3H mSATA only supports SATA2. The bandwidth will limit the mSATA3 SSD performance.
After enabling Intel SRT, the Write performance is 1.5~2 times faster.
Access Time is 76 times faster. The Write performance boost a lot in small files but max is lower than HDD.
For actual usage, system boot is 2~3 times faster.
I do hope GIGABYTE can upgrade mSATA slot to SATA3. It will boost SSD performance.

Temperature (Room is 28˚C)
Enter to OS Desktop - 33~37
