Anonymous users2024-02-07I recommend you to buy the Y450-PSE Centrino 2 book CPU P7450 (this P stands for the latest 45nm CPU with faster speed and lower power consumption).
The memory is Samsung 2G DDR3 1066 memory (at present, you go to the computer company to configure the machine, they generally give you the configuration of DDR2 800 memory, DDR2 and DDR3 are very different, 1066 is faster than 800 conversion).
geforce 130m gt 512m ddr3
Y450-PSE's leveling score In the above graphics card up to the CPU P7450 score is the pull back (so it seems that the Y450-TSI's CPU score is low).
Note that when buying a computer, you have to balance, and the more balanced the better. It's like a bottle, with a small mouth and a large body. When you go out to the water, the water doesn't come fast because your bottle is big. Because the mouth of the bottle is small.
Other CPUs such as TFOs don't make sense with graphics cards. So I highly recommend this one!
It's worth it if it's a little more expensive.
Many people recommend you to buy TSI, and indeed there are more people who buy this machine now. But its heat dissipation is the worst in the entire Y450 range. Poor heat dissipation seriously affects the life of the notebook
If LZ does consider the best factor, then TSI is a well-deserved second choice
I wish the landlord to buy his favorite notebook!

Anonymous users2024-02-06Y450A-TSI(H) (WHITE) is the most cost-effective in the whole system, now it's 5199, I use TFO white, and now it's very good, you can see mine.

Anonymous users2024-02-05Y450A-PSE(H) (Ash).
Y450A-PSE(W) (Gray).
Y450A-PEI(W) (Gray).
Of course, these three are a little better, and they are a little higher.
But the fever is a bit of a historical hazard.

Anonymous users2024-02-04Y450A-PEI(W) CPU supports Win7 virtual, and the funds are enough to start.
Y450A-TSI(E) is cost-effective, and there is room for upgrade of one memory.

Anonymous users2024-02-03If you want to buy, buy Y450A-TSI(E)! It's not very expensive.,It's not the best.,But it's not bad to use.,I've been looking at it recently.,Hehe,And this is win7 after the global release.,Bois is,You can install and activate win7 directly,Hehehe.。
Both Y450 and Y550 configurations are identical.
The high-end Y450-PEI Y550A-PEI are all P8700 processors, GT 240M independent graphics cards and 4GDDR3 memory. >>>More

From the perspective of hardware, as long as the machine is turned on, the hard disk is always turning, the CPU, graphics card, power supply, etc. are always heating, if it is turned on uninterruptedly, it must be a test of the service life of the hardware, don't listen to what others say about the computer of the Internet café once in a few years, I have managed the Internet café, you only see the computer of the Internet café closed once in a few years, then do you see the hardware of the Internet café changed once a few days? Especially for the motherboard, the motherboard is the first to be decommissioned after a long time of booting, and if it is not repaired in time, the damage of several small capacitors on the motherboard will lead to the burning of the hard disk CPU. My suggestion, if you want to boot for a long time, you should regularly check the capacitors on the motherboard, and regularly clean the dust in the case, you know, dust is one of the hardware killers, and moreover, dust seriously affects heat dissipation.
Nothing you shake with it on the line!
