GS40与GS45的区别总结：
- GS45功能类似GM45，显卡频率533MHZ，但可以降频到320MHZ，叫做4500MHD；GS40功能类似GL40，显卡频率400，叫做4500M。
- GS45和GS40的封装都是25mm x 27mm；GM45和GL40都是34mm x 34mm
- GS45外频能到1066，GS40只到800
- GS40不支持ITPM（好像类似防火墙），VT DMA（英特尔® I/O 虚拟分配技术 VT-d），TxT（内存保护一类），AMT（远程控制一类）
说GS40$28,GS45才$33，就想神舟为啥不用GS45呢？才贵50人民币吧？
查了一下，用SU2300+GS45的是商禧CV2300，竟然￥6399，郁闷了。（就多了个光驱和13“显示器）
在向各位大虾询问下，神舟为啥不用GS45呐
注：GS40的标志就是X4500显卡，GS45的标志是X4500HD 显卡。所谓HD，猜测是不是跟高清有关？还是说High什么东西？
