Motherboard: Except UD3P from Gigabyte, the other two models are not good. The motherboard UD3P is excellent in workmanship and quality, but the chipset of 770 is somewhat outdated, depending on your wishes.
Recommend one: Yingtai TA 880g HD 599.
Yingtai motherboard is the leading brand of second-line motherboard. Personally, I think that both quality and workmanship are better than Jabbo Hummer, and the motherboard combination of 880G+SB850 has superior performance. At present, most low-priced 880G integrated display motherboards are equipped with 880G+SB7 10 chipset. For example, the two 880G motherboards you selected are castrated products. So I suggest you use Gigabit UD3P or British TA880HD. Or you can choose 870 independent chipset motherboards, such as Yingtai TA870+￥699 and Huaqing 870 Extreme3￥699, which are all very good and cost-effective.
Hard disk is ok. As for the capacity, as long as you think it is enough.
The memory is ok, but Kingston is all fake, which of course also shows that Kingston's influence is still the first. It would be best if you can guarantee to get the genuine Kingston. If you can't guarantee to choose Wei Gang, you can.
Graphics card: 5550 can't compare with GTS250 and 4860 at all. The performance of 5550 is worse than that of GT240. You can't buy 4860 now unless you switch to Taobao. GTS250 is no longer worth buying. It is recommended to replace GTS450, the latest N-card new model GTS250. The price is the same as GTS 250, but the performance is better than GTS 250. Don't listen to some stupid 450 128 bit. You should see the performance of the 450. Its performance in 3D games is not inferior to that of 5770, and even exceeds it. Its technical specifications are basically the same as GTX460 except for wide bit width, excellent game performance and high cost performance.
How about domestic monitors? Do you know that Samsung is basically made in China? Basically, they are all made in China and made in Taiwan Province Province, with extremely low cost performance and poor quality. What you bought was just a shell. Choose brands with high cost performance such as AOC or Great Wall. If you like the Great Wall, you can choose AOC with excellent quality and no bad points.
Recommended: AOCIF 22 1299 2 1.5 inch IPS hard screen display. If you don't know what IPS hard screen is, you can Baidu it.
AOC 2330V+￥ 1299

AMD4 core platform, cost-effective.

Asus, a first-line motherboard manufacturer, produces smart motherboards that support one-button core opening. Adopt the latest 870 independent chipset, which is more stable and compatible with independent graphics cards.

Wei Gang's DDR3 1333 2G×2 4G dual channels have powerful performance.
