FomeLayer的个人资料

请教前辈们关于这套配置的建议以及一些其他相关问题（感谢）暑假兼职三个月可能存个一万左右，想自己配置一台新的机器。目前用的Y7000 1660ti感觉有点卡顿了开几个Excel都加载半天不知道是不是计划报废的原因（平时保养的还挺好的）。日常使用需求就是机器学习、数据处理、游戏开发、小建模渲染这些，有时间的话可能尝鲜一下新出的3A（大概率是没时间了...），然后个人比较喜欢白色，所以颜值上大概就是配白色的主机了。配置表如下，都是最近京东的价（但是暑假没法配出来，兼职完暑假才有点米米）显卡：七彩虹 RTX4070 Ultra W - 4800 主板：ROG STRIX B760-G GAMING WIFI D5小吹雪 - 1400 核心：i5 13600kf - 2100 内存：宏碁掠夺者（白色） 16GB*2 d5 6GHz C30 - 720 硬盘：致态TiPlus7100 1TB - 440 散热：Frozen Magic 240冰封幻境 - 290 电源：长城 650W 全模组 - 380 机箱：半岛铁盒（PADO）W1白色 - 130 合计：10260 然后想请教各位前辈一些问题：（1）最近浏览了很多装机视频、帖子，感觉大家都配置的很便宜，但是个人不太相信拼多多，所以如果只从京东购入的话这套配置是不是没啥压缩的空间了呀？看过微星的B760 MAX只要1200，但是B站上翻车视频也有一些，所以最终还是没有选择微星。（2）这款主板的IO散热装甲会不会挡住显卡呢？（3）不在双十一期间购入有可能这个价位实现吗？因为怕买的人多退的人也多，怕买到退货翻新的商品。（4）不考虑价格的话，整体配置上有没有什么问题呢？（比如CPU和显卡不合适或者CPU和内存不匹配这些问题）（5）白色机箱（非海景房）有没有什么推荐呢？感谢各位

代码分享：简易贝塞尔曲线前几天看了几篇关于手机动画效果的知乎文章，对贝塞尔曲线比较感兴趣，于是按照原理做了一个简易的示例，如果配合文件输入输出，也可以生成比例文件，不过由于楼主技术有限，不知道怎么指定文件相对位置，所以就只做了曲线显示部分啦。鼠标左键：开启/关闭移动指定的基点鼠标右键：添加新的基点鼠标中键：删除指定的基点鼠标中键：调整曲线点的精度变化方向效果如图啦：下面就贴代码啦(VS2019, C++11) #include <graphics.h> #include <list> #include <cmath> using namespace std;
