Ask for a quote for upgrading your computer and ask professional front line personnel to come in and

It's useless, there will actually be a gap, maybe it's cheaper, but more often it's expensive, such as dozens of dollars, so it's better for you to go to Zhongguancun ** or something like that yourself, there are many more things, isn't it better than copying it to you in this place? The one upstairs copied the price from **** to you.

It's useless to upgrade to a better CPU and then have a 2G memory, 512's graphics card is OK, it's best to change to a motherboard, it's very cheap now, add up to less than 1500 ·

Hard disk: SATA 7200 750G

Graphics: NVIDIA GeForce 9300M-GS HD PCI Express (256M).

Sound card: Creative Sound Blaster Audigy 2 ZS Platinum Pro

This configuration graphics card is the bottleneck...

The configuration replacement or upgrade of the first old machine is not cost-effective, the 1st generation is expensive, and the performance function is not good, it is recommended to change a poor dual-core to the 2nd generation 1G memory to a G31 motherboard with integrated graphics card 3 kinds of total ** in 600 yuan! It's like giving the machine a new heart.

In fact, if I'm not mistaken, the motherboard of the old machine of the landlord supports 2nd generation memory, if you really want to upgrade. I recommend going for value for money, not just for performance. Because both the chipset and the U of the motherboard limit the performance, and the CPU still has a considerable impact on the graphics card.
