need advice for a new laptop and a new computer ??!

[PHiLLeDINGUE]

first sorry for my bad english before it gets point out like usual...

I'm about to buy a new laptop for traveling and a new computer for when I'm home. I play about only online poker with my computers and do also a little data minning. I don't care about games or watching movies or what ever else, but might get into

My actual computer could be used as a server or something... I know my gf friends had something set up like that!! I already got my screens for the computers, but would probably need a traveling 2nd screen for the laptop(multi tabling) but I don't know what kind of set up would work better faster safer for me ??!

I haven't follow much about computer stuff in the last 5 years but I will understand what you're saying, no need to be fancy. Also I'm alot better at reading obv...

What would 5k budget look like ??

10k ??

thanks
