AMD is better value for money.
It is recommended to buy AMD's 5000+ black box or 5200+ black box, which is cost-effective.
Memory, you buy 2 1G DDR800 OK.
Hard disk 250g or 320g, each brand will not be much worse.
The rest is looking, 4500-5000 can be equipped with a very good machine.
I'm in the software, and I can only give you a little advice on the hardware.
-
AMD, the game must use AMD.
-
I use AMD, with a large memory to try!

The common fraction means that the numerator and denominator are multiplied by the same number at the same time, so the original fraction and the number after the universal fraction are equal.
When comparing fractions, you can first write the same denominator of different fractions, and then you can directly compare the size of the numerator to determine the size of the whole fraction.
1) 2 5 and 5 9, the least common multiple of the denominator is 45, the numerator and denominator of the previous fraction are multiplied by 9, and the numerator and denominator of the latter fraction are multiplied by 5, so they become 18 45 and 25 45 respectively, and it is obvious that the later fraction is larger, i.e. 2 5 5 9.
2) 6 7 and 13 14, the least common multiple of the denominator is 14, so you only need to write 6 7 as 12 14 to compare, it is obvious that the later fraction is larger, that is, 6 7 13 14.
3) 5 6 and 7 8, the least common multiple of the denominator is 24, so the general fraction is written as 20 24 and 21 24 respectively, and it is obvious that the following fraction is larger, that is, 5 6 7 8.

This is the common multiple of the denominator, for example, in the first group, the common multiple of 5 and 9 is the common multiple of 45, the common multiple of 6 and 8, the common multiple of 24, 7 and 14, and the common multiple of 14Then pass the points.

Life is all about ups and downs together.
-
First pass the denominator, turn the denominator into the same, and compare the numerators.
-
Divide first, and then compare the size of the molecules.
-
18 45 25 45 12 14 13 14 40 48 42 48 Divide the denominator first, and compare the numerators.

It's still like this after restarting, and it's generally okay to operate like this.
I guess you won't be embarrassed if you talk to your colleague on a computer, typical real-life phobia! You don't mind if I call you an "otaku", do you? >>>More

I just started to read your description that I thought she had a crush on you, but as I continued, I personally think she doesn't like you, because if she likes you, she should be very happy when you clearly tell her "you like her", but she doesn't seem to show you anything or even avoid you, so I think he keeps praising you as an ordinary friend. Then you said that she will also praise other boys in front of her friends, indicating that she should be a person who is used to praising others, I think she just treats you as an ordinary friend, and thinks that you have little chance, and if you continue to confess, you may lose her real friend, this is my advice, I hope to help you clear up the relationship.
