我跟我爸商量好了
要偷天換日一下

[url=images/smilies/emot/titter2.gif]screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='click here to open new window\nctrl+mouse wheel to zoom in/out';}" onmousewheel="return imgzoom(this);" onclick="if(!this.resized) {return true;} else {window.open(this.src);}" border=0 alt="" src="http://images/smilies/emot/titter2.gif" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='click here to open new window\nctrl+mouse wheel to zoom in/out';}">[/url]

我要他的主機板 cpu
然後在去買2gb ddr2 667
就等於我爸用我的amd3000+ 跟 再隨便買一張顯示卡放在我的amd3000+

因為我手頭很緊就只能這樣

[url=images/smilies/emot/shy2.gif]screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='click here to open new window\nctrl+mouse wheel to zoom in/out';}" onmousewheel="return imgzoom(this);" onclick="if(!this.resized) {return true;} else {window.open(this.src);}" border=0 alt="" src="http://images/smilies/emot/shy2.gif" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='click here to open new window\nctrl+mouse wheel to zoom in/out';}">[/url]


問題一
這樣我跑3d遊戲 例如:wow 效能會不會比以前好很多

問題二
還是我在存多一點我爸用我的6600 我在買張8600 gt

問題三
我該直接買ddr2 800嗎? 以後升級才方便?

問題四
我經費有限若買8400或者8500跑3d遊戲 例如:wow會比現在6600好很多嗎
若已經可以好很多我就不考慮8600 我夠用就好了
