Do you remember the price of Intel previous popular chipset 865?
The entry model was cost 120~130USD.
After that, P35/P45/P55/P67 chipset entry MB price was even higher.
The entry model was 160~180USD.
Of course, the MB components and spec were getting better and more features.
Many friends were complaining the high price and miss the chipset 865 time.
Most customers are more prefer parity MB. At late stage of Z68, you can see some 100USD boards.
In April, latest Ivy Bridge launched, Z77 boards are more parity.
Z77 just launched, many MB makers all released ~100USD Z77 MB.
These couple years, NoteBook, Pad and SmartPhone share the internet devices market.
It pushes DeskTop very hard. The market competition and price are going lower.
Z77 board price back to parity 865 dynasty which is good for users.
CPU is Intel Core i5-3570K
Clock is 3.4GHz, supports Turbo Boost 2.0 and max clock is 3.8GHz.
Latest 22nm plus 3Dtransistors technology, physical 4 Cores, 4C4T.
TDP 77W, L3 Cache is 6MB. Itís one of two Ivy Bridge K sku CPU.
i5-3570K price is mid-end Ivy Bridge CPU. If you donít OC, you can choose cheaper i5-3450.
This review is entry Z77. CPU using K series can improve the performance.
MB is GIGABYTE Z77-D3H. The price is around 135USD.
PCB is standard ATX, 30.5 X 24.4cm which is quite rare design in this price segment.
Of course, there are some cheaper Z77 boards. However, they may cut some display ports or shrink the PCB.
Does lower spec Z77 meet your requirement or budget? I suggest you better to study more before buying.
Z77-D3H is blue PCB and white slots. Blue is my favorite colors. Overall, itís good looking.
If you prefer the black PCB board, there is Z77X-D3H for you which is 20USD more expensive.
